The Journal is intended to cover some "frontier" aspects of materials science and, in particular, the most modern and advanced processes for the production of inorganic (semiconductors and metal alloys), organic (protein crystals) materials and "living" (in vitro) biological tissues, with emphasis on the fluid-dynamic conditions under which they are operated. The Journal focuses on the final properties of these materials as well as on fluid-mechanical aspects pertaining to the technological processes used to grow them. Some attention is devoted as well to all those problems of “structure/fluid” interaction that have extensive background applications in important fields such as marine, aeronautical and aerospace engineering.

Abstract At present, the optimization of the plunger mechanism is shale gas wells is mostly based on empirical methods, which lack a relevant rationale and often are not able to deal with the quick variations experienced by the production parameters of shale gas wells in comparison to conventional gas wells. In order to mitigate this issue, in the present work, a model is proposed to loosely couple the dynamics of gas inflow into shale gas wells with the dynamics of the liquid inflow. Starting from the flow law that accounts for the four stages of movement of the plunger, a dynamic… More >

Abstract
The effect of the tilt angle on mixed convection and related heat transfer in a “T” shaped double enclosure with four heated obstacles on the bottom surface is numerically investigated. The considered obstacles are constantly kept at a relatively high (fixed) temperature, while the cavity’s upper wall is cooled. The finite volume approach is used to solve the mass, momentum, and energy equations with the SIMPLEC algorithm being exploited to deal with the pressure-velocity coupling. Emphasis is put on the influence of the tilt angle on the solution symmetry, flow structure, and heat exchange through the walls. The following parameters… More >

Abstract Water-based drilling fluids can cause hydration of the wellbore rocks, thereby leading to instability. This study aimed to synthesize a hydrophobic small-molecule polymer (HLMP) as an inhibitor to suppress mud shale hydration. An infrared spectral method and a thermogravimetric technique were used to characterize the chemical composition of the HLMP and evaluate its heat stability. Experiments were conducted to measure the linear swelling, rolling recovery rate, and bentonite inhibition rate and evaluate accordingly the inhibition performance of the HLMP. Moreover, the HLMP was characterized through measurements of the zeta potential, particle size distribution, contact angles, and interlayer space testing. As… More >

Abstract In recent years, water collecting systems, with the associated advantages of energy saving and noise reduction, have become the foundation for the development of a scheme to optimize the structure of cooling towers. To explore the feasibility of this approach for mechanical draft cooling towers, a small-scale experimental device has been built to study the resistance and splash performances of three U-type water collecting devices (WCDs) for different water flow rates and wind speeds. The experimental results show that within the considered ranges of wind speed and water flow rate, the pressure drop of the different WCDs can vary significantly.… More >

Abstract The production performances of a well with a shale gas reservoir displaying a complex fracture network are simulated. In particular, a micro-seismic cloud diagram is used to describe the fracture network, and accordingly, a production model is introduced based on a multi-scale flow mechanism. A finite volume method is then exploited for the integration of the model equations. The effects of apparent permeability, conductivity, Langmuir volume, and bottom hole pressure on gas well production are studied accordingly. The simulation results show that ignoring the micro-scale flow mechanism of the shale gas leads to underestimating the well gas production. It is… More >

Abstract Electro-hydraulic proportional valve is the core control valve in many hydraulic systems used in agricultural and engineering machinery. To address the problem related to the large throttling losses and poor stability typically associated with these valves, here, the beneficial effects of a triangular groove structure on the related hydraulic response are studied. A mathematical model of the pressure compensation system based on the power-bond graph method is introduced, and the AMESim software is used to simulate its response. The results show that the triangular groove structure increases the jet angle and effectively compensates for the hydrodynamic force. The steady-state differential… More >

Abstract Torquigener albomaculosus, also known as the white-spotted pufferfish, is known for creating circular nests in the
underwater sand as part of the mating ritual. The nests are built by the males to attract females through the nest’s
impressive design and related ability to gather fine sand particles. As the fluid-dynamic processes associated with
these unique nests are still almost completely unknown, in the present study, an analysis has been conducted to
investigate how the geometric parameters related to the nest design influence the fluid velocity in its center. For
this reason, a geometric model of the nest consisting of 24… More >

Abstract Reservoirs characterized by high temperature, high-pressure, medium high cementation strength, low porosity, and low permeability, in general, are not affected by sand production issues. Since 2009, however, it is known that cases exists where sand is present and may represent a significant technical problem (e.g., the the Dina II condensate gas field). In the present study, the main factors affecting sand production in this type of reservoir are considered (mechanical properties, stress fields, production system, completion method and gas flow pattern changes during the production process). On this basis, a new liquid-solid coupled porous elasto-plastic 3D sand production model is… More >

Abstract In order to ensure the safe operation of the compressors used in water chillers, in the present study some interlock
protections have been added to the related design. These include a low pressure protection, a high pressure protection, an exhaust temperature protection and a differential pressure protection. Some tests have been conducted
by tuning the saturation suction and exhaust temperatures of the compressor through adjustment of the cold
source outlet temperature and the ambient temperature. The results show that the ambient temperature increases
with decreasing device load and increasing fan speed under the same saturated suction temperature; the device

Abstract Sodium-alginate (SA) based nanofluids represent a new generation of fluids with improved performances in terms
of heat transfer. This work examines the influence of the nanoparticle shape on a non–Newtonian viscoplastic
Cu–nanofluid pertaining to this category. In particular, a stretching/shrinking sheet subjected to a transverse magnetic field is considered. The proposed Cu–nanofluid consists of four different nanoparticles having different
shapes, namely bricks, cylinders, platelets, and blades dispersed in a mixture of sodium alginate with Prandtl
number Pr = 6.45. Suitable similarity transformations are employed to reduce non–linear PDEs into a system
of ODEs and these equations and related boundary conditions… More >

Abstract A method for the treatment of hazardous waste drilling fluids, potentially leading to environmental pollution, is considered. The waste drilling fluid is treated with an inorganic flocculant, an organic flocculant, and a pH regulator. The profile control agent consists of partially hydrolyzed polyacrylamide, formaldehyde, hexamethylenetetramine, resorcinol, phenol, and the treated waste drilling fluid itself. For a waste drilling fluid concentration of 2500 mg/L, the gelling time of the profile control agent is 25 h, and the gelling strength is 32,000 mPa.s. Compared with the profile control agent prepared by recirculated water under the same conditions, the present profile control agent displays better… More >

Abstract When aluminum alloys are coupled with dissimilar materials, they often act as corrosion anodes and are suscepted to accelerated corrosion. Therefore, deepening our knowledge of such corrosion phenomena, related
mechanisms, and elaborating new prediction model is of great theoretical and practical significance. In this paper,
such mechanisms are explained from both macroscopic and microscopic points of view by considering several
aspects such as the second phase particle type, grain size, and environmental ions. More specifically, different perspectives on such a problem are elaborated, which take into account: the properties of the coupling pair materials,
geometrical characteristics, environmental media characteristics, the… More >

Abstract Oxygen-reducing air flooding is a low-permeability reservoir recovery technology with safety and low-cost advantages. However, in the process of air injection and drive, carbon in the air is oxidized through the crude oil reservoir to generate CO2, and this can cause serious corrosion in the recovery well. In this study, experiments on the
corrosion of J55 tubular steel in a fluid environment with coexisting O2 and CO2 in an autoclave are presented. In
particular, a weight loss method and a 3D morphometer were used to determine the average and the local corrosion rate. The corrosion surface morphology and composition were… More >

Abstract Rutting of asphalt pavement occurs earlier and is more serious under the increasingly heavy traffic load conditions that can be found in subtropical monsoon climate regions. High modulus asphalt concrete (HMAC) with excellent anti-rutting and anti-fatigue properties is generally used to mitigate this issue. Given the relatively high cost of the additives used in this type of asphalt, in this study the feasibility of using recycled asphalt mixture (RAP) and Trinidad lake asphalt (TLA) for the preparation of HMAC is considered. The mineral composition of the RAP is first analyzed, then the TLA modified asphalt with different levels of RAP… More >

Abstract Low-Tension-Foam (LTF) flooding is an emerging enhanced oil recovery technique for low-permeability carbonate reservoirs. Foam capacity is closely related to the salinity environment (or, equivalently, the phase behavior of the oil/water/surfactant system). Therefore, the interactions between microemulsion and foam components are of primary importance in the LTF process. In this study, the phase behavior of an oil/water/surfactant system under equilibrium is analyzed, firstly by assuming perfect mixing. Meanwhile, the formation kinetics of microemulsion are monitored through a novel low-field NMR technique, which is able to provide quantitative assessment on the microemulsion evolution characteristics. Then, foam stability is examined in the… More >

Abstract A dynamic triaxial instrument was used to study the effects of different concentrations of sodium chloride and stress amplitudes on the dynamic properties of an expansive soil under cyclic loading. In particular, four parameters were considered in such a parametric investigation, namely, hysteresis curve morphology characteristic non-closure degree εp, the ratio of the short and long axis α, the slope of the long axis k and the enclosed area S. The results show that with an increase in the sodium chloride concentration, the soil particle double electric layer becomes thinner, the distance between soil particles decreases, and the whole sample… More >
