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 Desert photovoltaic, PV, installations experience significant efficiency losses due to dust accumulation, which also promotes localized overheating, known as hotspots, caused by uneven solar irradiance and partial cell shading. These hotspots can accelerate material degradation and increase the risk of permanent panel damage. This study presents an autonomous maintenance strategy based on a cooperative swarm of unmanned aerial vehicles, UAVs, enabling contactless dust removal and active hotspot cooling. The approach combines high-fidelity computational fluid dynamics to characterize aerodynamic downwash for effective dust detachment with fluid–structure interaction analysis to verify the structural integrity of PV panels… More >

Abstract Flows over rotating disks are central to numerous engineering applications, including turbines, rotating sensors, and advanced cooling devices, where the incoming fluid often strikes the disk at an angle. This study examines magnetohydrodynamic (MHD) oblique slip flow toward a rotating disk, accounting for critical effects such as velocity slip, thermal slip and thermal radiation. In particular, the Cattaneo–Christov heat flux model is used to capture thermal relaxation phenomena, frequently overlooked in prior analyses, while employing a uniform transverse magnetic field to regulate both momentum and heat transfer. Using similarity transformations, the governing nonlinear equations are… More >

Abstract The rapid development of space transportation systems and high-speed military aircrafts have intensified interest in turbulent separated flows, particularly under transonic and supersonic conditions. Such flows commonly arise downstream of sudden expansions, where separation and subsequent reattachment generate strong shear layers, increased drag, and a low-pressure recirculation region at the base. In this study, the control of base pressure downstream of a sudden expansion is investigated numerically using a passive bullet-shaped rib. A jet issuing from a nozzle is discharged abruptly into a duct of 25 mm diameter, producing a separated flow with pronounced recirculation.… More >

Abstract To address the thermal management challenges associated with localized high heat flux in electronic chips, this study proposes a bionic spider-web microchannel heat sink using deionized water as the coolant. Numerical simulations are conducted for two configurations, one with pinfins at the hotspot (Model A) and one without pinfins (Model B). The effects of Reynolds number and hotspot heat flux on flow distribution, pumping power, thermal resistance and temperature uniformity are systematically analyzed. Results show that the flow distribution varies significantly among channels, with higher flow rates near the inlet. Increasing the Reynolds number raises More >

Abstract Perforated partition walls are widely employed in complex underground transportation systems to mitigate tunnel pressure waves, harness train-induced piston wind for reduced ventilation energy consumption, and support emergency operations. Building on orifice flow theory, this study develops a one-dimensional flow model for tunnels equipped with perforated partition walls. The model is applied to examine the aerodynamic performance of such walls in extra-long tunnels through a comprehensive parametric analysis, considering the presence of openings, opening ratio, spacing, and spatial arrangement. The results demonstrate that, for opening ratios, defined as the ratio of the perimeter of a… More >

Abstract To investigate transient flow instabilities in parallel-channel regenerative cooling systems subjected to nonuniform heat flux, a three-dimensional transient numerical model was developed to couple variations in supercritical fluid thermophysical properties with endothermic pyrolysis kinetics. The spatiotemporal evolution of RP-3 fuel within parallel channels was analyzed, and the role of a midstream interconnection structure in mitigating flow maldistribution was clarified. During the initial heating stage, the viscosity reduction of the supercritical fuel produced a drag-reduction effect that temporarily maintained a nearly uniform flow distribution. As the wall temperature increased and the pseudocritical region approached, the sharp… More >

Abstract As coal extraction advances to greater depths, a refined understanding of the coupled evolution of involved physical effects and mechanisms in gas-bearing coal under excavation-induced disturbances becomes indispensable. In this context, “chain evolution” characterizes the progressive and interdependent interplay among stress redistribution, damage propagation, and seepage adjustment. Building upon a seepage–stress–damage coupling model for gas-bearing coal, and supported by triaxial compression tests for validation, this study explores multifield evolution during roadway excavation across lateral pressure coefficients

Abstract The effective management of gas–liquid two-phase flow, emerging within the microchannels of proton exchange membrane fuel cells (PEMFCs) during operations, is crucial for improving energy conversion efficiency. In this study, the influence of surface wettability is examined for hydrophilic and hydrophobic conditions through a visualization-based experimental setup focused on single-droplet dynamics. The impact of key parameters on droplet behavior is systematically explored, while the mechanisms underlying the observed flow patterns are elucidated and the coupling among governing physical factors is clarified. The results show that, under comparable conditions, hydrophobic surfaces exhibit larger advancing contact angles More >

Abstract Traditional parallel straight microchannels are limited by low heat flux density and non-uniform flow distribution. From a system optimization perspective, incorporating surface grooves provides an effective means to enhance solid-liquid interaction and improve overall performance. Using water as the working fluid, this study numerically investigates the coupled effects of inlet flow rate, groove number, and groove spacing on the thermo-hydraulic behavior of groove-type microchannel heat sinks. The results reveal a fundamental trade-off between heat transfer enhancement and hydraulic resistance. Increasing coolant velocity significantly improves heat dissipation, but also raises the pressure drop, affecting pumping power… More >
