Fluid Dynamics and Materials Processing is an essential reading for all those concerned with complex fluids, multiphase flows and the intersection of fluid dynamics with materials processing and/or with the more general field of engineering optimization. It features original theoretical, computational, and experimental investigations. All subjects where a material, at a certain stage of its “life”, is in a fluid state, behaves as a fluid (e.g. many types of granular media) or interacts with a fluid should be considered relevant to FDMP. Relevant examples include (but are not limited to) the most modern and advanced processes for the production of inorganic (semiconductors, metal alloys, foams, plastics, polymers, ceramic materials, cement, asphalt and resins of various kinds), organic (protein crystals, drugs and medicines) materials and "living" (in vitro) biological tissues. We are especially interested in those studies where emphasis is put on the fluid-dynamic conditions under which a material is operated. However, FDMP also welcomes manuscripts dealing with more fundamental aspects such as the rheological behavior of multiphase systems or the convective currents that are produced in a fluid as a result of the thermal, chemical and/or mechanical stimuli typically applied in various processing or manufacturing methods (e.g. thermal gradients, shaking, mixing, etc). 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, chemical, aeronautical and aerospace engineering and the oil sector, i.e. all those cases where fluid-dynamic analysis is instrumental in guiding the design/optimization of the considered systems (or related components) and the selection of the required “materials”.

Abstract The complex interplay of heat transfer mechanisms, namely conduction, natural convection, and radiation, within hollow block roofs exposed to solar irradiation gives rise to an inherently nonlinear thermal exchange problem. A key yet insufficiently explored question is the extent to which this nonlinearity governs the macroscopic thermal behavior of roofing systems. In this study, a computational investigation is conducted on two roof configurations incorporating five hollow block geometries representative of common construction practices in hot climatic regions. The objective is to identify the optimal design capable of minimizing heat losses and thereby enhancing the overall… More >

Abstract Low-permeability conglomerate reservoirs are characterized by complex pore structures and poor sweep efficiency, making the optimization of carbon dioxide-water alternating gas (CO2-WAG) injection critical for enhanced oil recovery. To evaluate the displacement performance of CO2-WAG and determine the lower limit of effectively swept pore throats, this study presents long-core flooding experiments conducted on cores from the KS Formation of the B Oilfield in the Junggar Basin under reservoir conditions (20.1 MPa and 58°C). Continuous CO2 flooding and CO2-WAG schemes with varying cycle numbers and gas-water ratios (GWRs) were systematically compared. In situ online nuclear magnetic resonance (NMR) monitoring… More >

Abstract To overcome the inherent limitations of conventional post-cementing acidification, including limited acid penetration into the formation and the potential impairment of zonal isolation, a novel pre-cementing acidification approach is proposed. This method aims to remove near-wellbore formation damage before cementing operations. Its feasibility, however, critically depends on the physicochemical compatibility between residual acid and the subsequent cementing fluids, namely spacer fluids and cement slurries. In this study, a comprehensive series of laboratory experiments was conducted to evaluate the effects of residual acid on flushing efficiency, rheological compatibility, and thickening time. The results show that residual… More >

Abstract This study investigates the microscopic mechanisms governing water transport in kaolinite-rich nanoporous media, a topic of considerable importance for shale gas recovery, seepage in fine-grained soils, and the migration of contaminants in low-permeability geological formations. To this end, molecular dynamics (MD) simulations are performed on slit-shaped kaolinite nanopores with different degrees of surface wettability in order to elucidate the influence of solid-liquid interactions on the structure and dynamics of confined water. The analysis focuses on the spatial arrangement, molecular orientation, and transport characteristics of water within the nanopores. The simulations show that confinement gives rise… More >

Abstract This study investigates the leakage and dispersion behavior of high-pressure CO2 in long-distance pipelines using computational fluid dynamics (CFD) coupled with a regional-scale modeling framework. The influence of key operational and environmental parameters, including transport temperature, pressure, pipeline diameter, leak orifice size, and ambient wind speed, is systematically examined, with particular emphasis on their role in governing the spatial extent of solid CO2 formation. The results indicate that the evolution of the leakage flow field is governed by a strong coupling between thermodynamic effects and fluid dynamic processes. Elevated temperatures delay the formation of the Mach… More >

Abstract A computational fluid dynamic (CFD) numerical framework is established in this article to comprehensively uncover the flow evolution laws and gas-liquid phase-change heat transfer mechanisms of vertical falling film with high Reynolds numbers (Re). Systematic numerical analysis are carried out to characterize the liquid film spatial distribution, flow velocity field, internal turbulent vortex structures and comprehensive heat transfer behaviors. The swirl-induced coherent structures are identified using velocity vectors and vortex-detection criteria, and the influences of swirl angle, channel width, and platform height on film thickness distribution and thermal performance are examined. Model validation is performed through… More >

Abstract Seepage-induced rheological deformation represents a critical factor governing the long-term stability of coastal soft-soil excavations subjected to intense rainfall infiltration and groundwater fluctuations. This study elucidates the individual and interactive effects of seepage pressure and seepage duration on the time-dependent deformation behavior of undisturbed mucky soft soil containing medium-fine sand, collected from a deep foundation pit. A comprehensive experimental campaign based on triaxial seepage-shear rheological testing for a confining pressure of 180 kPa is presented, encompassing sixteen combinations of seepage pressure and duration together with a directly measured zero-seepage reference condition. Three replicate specimens are… More >

Abstract A two-dimensional Computational Fluid Dynamics (CFD) model, grounded in classical nucleation theory, is developed to investigate CO2 frosting and the associated heat transfer under cryogenic conditions. The model integrates gas–solid phase-change kinetics with multiphysics transport equations to capture the coupled phenomena governing frost formation. The Peng–Robinson equation of state is employed to predict CO2 frost points in binary mixtures, with model predictions validated against experimental data, yielding errors in frost thickness and thermal conductivity below 15%. The results demonstrate that decreasing the cryogenic wall temperature from 160 K to 150 K increases the average frost thickness… More >

Abstract Oscillating-wing power extractors (OWPEs) are an alternative to rotary wind turbines for small- and medium-scale renewable energy applications. However, the aeroacoustic response of such systems remains largely unexplored. In this study, the power extraction performance and near-field aeroacoustic characteristics of an OWPE are numerically investigated using transient computational fluid dynamics (CFD) simulations coupled with the Ffowcs Williams–Hawkings (FW–H) acoustic model at a Reynolds number Re of 8.58 × 104. Two important operating parameters, namely the pitching amplitude θo and reduced frequency f*, are varied systematically, and the corresponding near-field sound pressure level (SPL) is measured at… More >

Abstract This study develops a particle-fiber-powder composite temporary plugging system and systematically investigates the dynamic plugging behavior of single-component, binary, and ternary formulations to elucidate the mechanisms governing plug formation and optimize material composition for diversion fracturing applications. Conventional temporary plugging materials often exhibit inadequate plug formation, limited pressure-bearing capacity, and poor plugging stability, compromising stimulation effectiveness in heterogeneous reservoirs. Experimental results show that neither the particle-only nor the particle-powder system can establish a stable load-bearing structure, resulting in poor plugging performance. In contrast, fiber incorporation fundamentally transforms weak particle bridging into a mechanically stable plug,… More >
