Liquid jets impinging on surfaces are widely found in various industrial processes, such as spray painting, high-pressure water jets, and dishwashers. The liquid can break up into sprays with discrete, small-scale features that difficult to reveal. This work proposes a multiscale solver OpenFOAM achieves two-way conversion by capturing the large-scale interface using Volume of Fluid (VOF) approach tracing droplets Discrete Phase Model (DPM). By comparing VOF–DPM standard VOF solver, conservation mass momentum, well accuracy new verified. Considering that, spraying collisions mainly occur after jet breaks multiple droplets, we simplify model focus collision walls at different speeds contact angles, corresponding materials. results indicate speed increases, splashing becomes more likely spurt further. It is also an increase angle will mean diameter discrete droplets. Overall, this accurately capture both interfaces offering wide application prospects.

Published: April 18, 2025

Abstract This study explores the optimization of Casson fluids, focusing on role ternary hybrid nanofluids in enhancing thermal efficiency industrial and engineering applications. Specifically, impact thermophoretic particles chemical reactions bioconvective nanofluid flow through a vertical microchannel embedded with porous media is examined. The governing equations are reduced using similarity transformations, resulting nonlinear solved Runge–Kutta–Fehlberg 4th 5th order method. findings reveal that increasing constraint leads to decrease nanoparticle concentration, highlighting forces particle movement deposition. Additionally, parameter causes reduction velocity, which observed affect overall fluid dynamics system. presence variable conductivity enhances field, suggesting temperature distribution can be significantly improved. Moreover, volume fraction distribution, indicating positive correlation between concentration efficiency. On other hand, results mass transfer rate, emphasizing trade‐off enhanced performance transport. These valuable for design advanced micro‐cooling devices, micro‐heat exchangers, micro‐pumps, macro mixing technologies, where both critical.
