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 This study investigates the influence of valve-orifice geometry on the dynamic response and synchronization performance of master-slave hydraulic cylinder systems, with particular emphasis on transient fluid-structure interactions in electrically driven hydraulic systems. A combined theoretical and experimental investigation is conducted to elucidate the interaction between orifice geometry and the transient response of the master-slave system. A dynamic coupling model is developed that incorporates the geometry-dependent area gradient (dA/dx) and mechanical feedback delay, enabling the underlying mechanisms of pressure surges, post-surge time lag, and disturbance recovery during nonlinear throttling to be identified. Based on these mechanisms,… More >

Abstract A coupled seepage-stress numerical model, based on the finite element method and groundwater seepage theory, is implemented to evaluate the effectiveness of drainage pressure relief for controlling basement uplift under varying groundwater and structural conditions. The model is used to systematically investigate the effects of groundwater-level fluctuations, the pressure-limiting total head of drainage holes, and diaphragm wall embedment depth on pore-water pressure, drainage demand, groundwater drawdown, and ground deformation. The results show that drainage pressure relief effectively reduces and stabilizes pore-water pressure beneath the foundation, thereby mitigating the risk of basement uplift. Under fluctuating groundwater… More >

Abstract Liquefied Natural Gas (LNG) is a clean and efficient energy source; however, due to its high flammability and explosive potential, accidental releases can lead to severe fire and explosion hazards as well as environmental damage and casualties. To evaluate and enhance the predictive capability of dispersion models, the accuracy of the Phast™ software was validated using experimental data from the Falcon series, i.e., five large-scale (up to 66 m3) pressurized LNG release tests originally conducted by the Lawrence Livermore National Laboratory (LLNL). Using Phast™, we systematically investigated the effects of key environmental and operational parameters, including… More >

Abstract This review examines recent advances in the aerodynamic analysis and dynamic stability of high-speed aerospace vehicles, with particular emphasis on surface pressure distributions, aerodynamic stability derivatives, and complex flow behavior under supersonic and hypersonic conditions. The review first outlines the fundamental physical mechanisms governing high-speed aerodynamics and then critically surveys analytical, numerical, computational fluid dynamics, and experimental approaches for predicting aerodynamic characteristics. Particular attention is given to pressure, stiffness, damping, and rolling derivatives, as well as flow behavior in suddenly expanded ducts, which are relevant to the aerodynamic performance and stability of high-speed vehicles.

Abstract This study presents an integrated optimization framework that combines long short-term memory (LSTM) load forecasting with hybrid optimization to improve the energy efficiency of central air-conditioning cooling-source systems. Grey-box energy consumption models are first established for chillers, pumps, and cooling towers based on their underlying operating mechanisms, with model parameters identified using the least-squares method. An LSTM model is subsequently trained using 96 days of hourly operational data to predict the short-term cooling load, achieving a root mean square error of 9.7 kW. The predicted cooling load is then used to constrain the system-level optimization. More >

Abstract The thermo-hydraulic performance of three wavy microchannel heat-sink architectures, namely single-inlet single-outlet (SISO), single-inlet dual-outlet (SIDO), and branched single-inlet dual-outlet (BSIDO) configurations, are numerically investigated using deionized water and low-concentration Fe3O4 nanofluids for electronic thermal management. Steady-state laminar flow and heat transfer simulations are performed over Reynolds numbers of 700–1300 for Fe3O4 nanoparticle concentrations of 0.1%, 0.3%, and 0.5%, within a consistent numerical framework and under prescribed wall thermal boundary conditions. The Nusselt number, friction factor, and Performance Evaluation Criterion (PEC) are employed to assess the coupled thermal and hydraulic performance of the different architectures and to… More >

Abstract This study investigates and optimizes alternating slug injection strategies for heterogeneous phase combination flooding in strongly heterogeneous, ultra-high-water-cut reservoirs. Integrated parallel core-flooding and three-dimensional physical simulation experiments were performed to evaluate three injection strategies at a total slug volume of 0.6 PV: conventional heterogeneous phase combination flooding, alternating injection of heterogeneous phase combination system/polymer slugs, and alternating injection of heterogeneous phase combination system/heterogeneous system slugs. The core-flooding results demonstrate a clear advantage of alternating injection, with incremental recovery factors of 27.4%, 30.8%, and 34.4% for the three strategies, respectively. Alternating injection also produced a pronounced More >

Abstract This study develops and investigates an innovative composite rotor-stator hydrodynamic cavitation device designed to enhance cavitation generation for wastewater remediation. The device integrates double-row stator shear teeth with cylindrical pits on the rotor, enabling the simultaneous generation of flow-separation and vortex cavitation in both radial and circumferential directions. Transient two-phase flow simulations conducted on two orthogonal cross-sections reveal the synergistic evolution and coupling of these two cavitation modes, overcoming the single-direction perspective adopted in previous studies. Rhodamine B degradation experiments are then employed to indirectly characterize cavitation intensity and assess the reactor performance. The effects More >

Abstract This study elucidates the coupled damage mechanisms induced by retrograde condensation and water blocking in low-permeability edge-bottom water condensate gas reservoirs and develops an optimized CO2 injection strategy for simultaneously enhancing hydrocarbon recovery and geological carbon storage. Using the K condensate gas reservoir in the Junggar Basin as a case study, nuclear magnetic resonance (NMR) measurements and long-core displacement experiments are integrated to characterize the evolution of water-lock and retrograde-condensation damage across pore and core scales and to unravel the mechanisms governing its mitigation by CO2 injection. The results reveal a pronounced synergistic interaction between the… More >

Abstract In this experimental study, the pore-scale interaction between a flowing oil-in-water emulsion and a porous-medium grain are considered to elucidate how the viscosity ratio between the oil and continuous phases governs the resulting flow behavior. Relevant microfluidic experiments were conducted using sodium dodecyl sulfate as the emulsifier and three types of dimethyl silicone oil with different viscosities as the dispersed oil phase. The results show that, upon interacting with a porous-medium grain, a single oil-in-water emulsion can undergo three distinct flow regimes: deformation and passage through the grain, incomplete breakup, and complete breakup. The transitions… More >

Abstract This study investigates the fluid forces acting on brush wires in high-speed liquid-cooled slip rings by combining computational fluid dynamics (CFD) simulations with theoretical modeling. The study first characterizes the two-dimensional (2D) and three-dimensional (3D) flow fields within a rotating annular domain representative of a liquid-cooled slip ring, and then uses a simplified single-wire model to quantify the hydrodynamic forces acting on a rigid brush wire over a range of rotational speeds. The results show that the normal pressure force becomes the dominant contribution to the total fluid force at high rotational speeds. Comparisons among More >
