We present a fully compressible single-fluid volume of fluid (VOF) solver with phase change for high-speed flows, where the atomization liquid can occur either by aerodynamics or effect local pressure. The VOF approximation among non-miscible (non-condensable gas) and mixture two fluids (liquid vapor) represents core jet its atomization. A barotropic model is used in combination equation state ...

The breakup dynamics of a capillary bridge on hydrophobic stripe between two hydrophilic stripes is studied experimentally and numerically using direct numerical simulations. formed from an evaporating water droplet wetting three neighboring chemically patterned surface. By considering the process in phase space representation, can be evaluated without uncertainty determining precise time. simu...

A numerical model utilizing the volume of fluid (VOF) method is proposed to simulate transient shape changes deposit front, considering diffusion-limited electrodeposition process. Modeling equations are accurately handle transport phenomena in both electrolyte (fluid) and (solid). Transient evolutions field structures, including flow, concentration, electric current density, potential, compute...

Abstract Siphon-shaft spillways are constituted by covering above a shaft spillway with hood that creates siphonic pressure. This study focused on the aeration flow through aerator holes placed to prevent cavitational damage in high-head siphon-shaft spillways. Three-dimensional computational fluid dynamics (CFD) technique using finite-volume method solve Reynolds-averaged Navier–Stokes (RANS) ...

The seakeeping performance of a damaged ship is highly correlated to the wave incident direction. Therefore, predicting motion responses under various incoming waves important. In this study, DTMB 5415 model investigated by focusing on its roll beam condition. an angle (?) 180° widely studied experimentally and numerically. But behaviours ? = 0° remain unknown. This study aims analyse rarely vo...

The viscosity of adiponitrile waste liquid is as high 1000 cp. It challenging to spray and atomize the normally. Based on coaxial three-channel pneumatic atomizer, a two-stage supersonic steam atomizer proposed in this paper, atomization process simulated by Fluent software. Compared with traditional simulation method, Volume-of-Fluid Discrete-Phase-Model (VOF-DPM) bi-directional coupling model...
