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 utilization of water-cooled electric furnace ferronickel slag (EFFS) in concrete remains constrained by its intrinsically low pozzolanic reactivity as a supplementary cementitious material (SCM) and its inadequate volumetric stability when employed as aggregate. This study systematically investigates the compositional characteristics of this slag across different particle-size fractions and proposes a wet-grinding activation strategy to enhance its pozzolanic performance. In particular, cement pastes incorporating 10%, 30%, and 50% ultrafine EFFS derived from three original size fractions are comprehensively evaluated in terms of rheological behavior, compressive strength, hydration characteristics, and microstructural evolution. The results demonstrate pronounced… More >

Abstract Underwater bio-inspired robots have emerged as a promising alternative to conventional propeller-driven autonomous underwater vehicles and remotely operated vehicles because of their potential for high propulsive efficiency, superior maneuverability, reduced acoustic signatures, and enhanced environmental adaptability. Unlike rigid propellers operating under approximately steady inflow conditions, bio-inspired propulsion relies on strongly unsteady hydrodynamic mechanisms, including vortex generation and shedding, added-mass effects, boundary-layer evolution, and flexible fluid–structure interaction (FSI). These processes fundamentally govern thrust production, energy conversion, and maneuvering performance, yet a systematic synthesis connecting hydrodynamic mechanisms with engineering implementation remains limited. This review addresses that gap… More >

Abstract This study presents a comprehensive numerical investigation of laminar forced convective boundary layer flow over a non-isothermal wedge immersed in an Al2O3-Cu/water hybrid nanofluid, with relevance to thermal management in high-temperature aerospace systems, microelectronic cooling devices, and nuclear safety components. The research evaluates the combined effects of exponential space-dependent heat generation (ESDHG), thermal radiation, and uniform surface transpiration (suction/blowing) on the hydrothermal performance of the system. The governing non-similar differential equations, incorporating the Rosseland diffusion approximation, are solved using the high-accuracy Keller-box method. The numerical results indicate that increasing the wedge angle parameter compresses the momentum More >

Abstract A combined asymptotic and characteristic-based computational framework is developed to investigate unsteady compressible flow response in solid rocket motor (SRM) chambers subjected to exit-plane disturbances and steady sidewall mass injection. The formulation integrates a low-Mach-number asymptotic reduction of the governing equations with a time-accurate numerical solution of the parabolized Navier–Stokes equations, employing characteristic-based boundary conditions to ensure physically consistent wave reflection and transmission at chamber boundaries. Controlled exit-plane pressure forcing is imposed under non-resonant and near-resonant conditions to examine acoustic–vorticity coupling mechanisms within slender SRM geometries. The computational framework is verified and validated against analytical… More >

Abstract Optimizing the utilization of explosive detonation energy through bench blasting is central to improving both the efficiency and safety of open-pit mining operations. However, conventional blasting geometries often produce a non-uniform energy distribution, with excessive toe burden at the bench base and insufficient crest burden near the slope top, conditions that can significantly increase the risk of flyrock. This study proposes an air-decked charge configuration to mitigate these imbalances and enhance blast performance. A coupled numerical framework integrating the Particle Blast Method, Finite Element Method, and Smoothed Particle Hydrodynamics is employed, complemented by high-speed photographic More >

Abstract Serpentine heat exchangers are extensively used in energy and chemical engineering owing to their compact geometry and high thermal performance. To improve their efficiency, three-dimensional numerical simulations are conducted using the SST k-ω turbulence model for both serpentine and straight tubes fitted with twisted tape inserts. Three twist ratios (y = 5.77, 8.57, 12.48) are examined across a Reynolds number range of 10,000 to 22,000. Results show that the average Nusselt number increases with Reynolds number, while the friction factor decreases. In particular, due to curvature-driven secondary motions, serpentine configurations consistently outperform straight tubes in thermal… More >

Abstract Injection damage in the M tight oil reservoir is controlled by the coupled effects of inorganic scaling and organic fouling at the pore scale. To clarify the governing mechanisms, this study combines long-duration core flooding, water-chemistry compatibility analysis, and thermodynamic scale prediction with NMR T2 spectroscopy, mercury intrusion capillary pressure, SEM-EDS characterization, and factor-controlled microfluidic visualization that reproduces reservoir pore geometry and wettability. Core flooding tests reveal permeability reductions of 61 to 73 percent after 12 to 24 hours of injection, indicating progressive contraction of effective flow channels. NMR T2 spectra demonstrate strong pore-size selectivity: small… More >

Abstract This study presents an integrated multi-scale framework for predicting gas entrainment and flow behavior in coalbed methane production systems under gas-liquid two-phase flow conditions. The approach combines three-dimensional computational fluid dynamics simulations, reduced-order modeling, and machine-learning-based prediction to achieve both high physical fidelity and computational efficiency. Such an improved strategy stems from a specific need. As coalbed methane extraction increasingly encounters complex multiphase flow conditions, accurate characterization of gas entrainment has become essential for improving production stability and optimizing downstream gathering and separation systems. In practice, the flow entering rod pumps frequently deviates from the… More >

Abstract Internal cooling galleries are widely employed to mitigate piston thermal loads in gasoline engines, where their configuration plays a critical role in temperature distribution and component durability. In this study, Cradle CFD was coupled with the Conjugate Heat Transfer (CHT) and Volume of Fluid (VOF) multiphase approaches to investigate the effects of inlet angle and guide vane geometry on piston thermal performance. The SST k-ω turbulence model was adopted to resolve the transient flow behavior associated with reciprocating motion, while the Box-Behnken design methodology was applied to develop empirical correlations for optimization.

Abstract To address the short peak-production period and limited incremental recovery commonly encountered during chemical flooding of high water-cut reservoirs, this study investigates the dynamic evolution of displacement fronts and their controlling factors through laboratory experiments and numerical simulation. Two-dimensional plate flooding experiments were first conducted to characterize the evolution of the oil bank in homogeneous and heterogeneous reservoirs, revealing a four-stage process of formation, enrichment, mobilization, and residual depletion. Based on water-cut behavior, the flooding process was further classified into early-response, peak-response, and late-response stages. A three-dimensional heterogeneous reservoir model was subsequently developed to quantify… More >

Abstract Slurry transport is a critical multiphase-flow process in mining, metallurgy, and dredging applications, where hydraulic efficiency, particle-induced wear, cavitation erosion, and structural vibration are strongly coupled. This topic-focused review synthesizes recent advances in centrifugal slurry pump design optimization from the perspectives of wear-resistant surface engineering, hydraulic design, structural dynamics, intelligent optimization algorithms, and multiphysics simulation. Unlike earlier reviews that primarily addressed hydraulic performance, erosion wear, flow visualization, or numerical modeling in isolation, the present work adopts a lifecycle-oriented perspective. Representative studies are critically evaluated according to reported efficiency improvements, wear-rate and material-loss reduction, cavitation and… More >
