TL;DR: In this article, three numerical methods, namely, volume of fluid (VOF), simple coupled volumetric fluid with level set (S-CLSVOF) and S-clsVOF with the density-scaled balanced continuum surface force (CSF) model, have been incorporated into OpenFOAM source code and validated for their accuracy for three cases: (i) an isothermal static case, (ii) isothermal dynamic cases, and (iii) non-isothermal dynamic case with thermocapillary flow including dynamic interface deformation.

TL;DR: Simulation results showed that widening of cavitation zone and altering of acoustic streaming velocity and direction near the sonotrode tip are responsible for the enhancement of Cavitation treatment efficiency.

TL;DR: In this paper, a global numerical simulation was performed for the induction heating Top-Seeded Solution Growth (TSSG) process of SiC. The simulation results showed that the contributions of free surface tension gradient and the electromagnetic body force to the melt flow are significant.

TL;DR: In this paper, the authors investigated the mechanism of surface vortex formation and free surface deformation in an unbaffled stirred vessel with on-axis and eccentric impellers having four paddle blades.

TL;DR: In this article, the authors examined the effect of twisting angle on the flow pattern through PIV experiments and numerical simulation using water model and revealed that the twisting angle affects the strength and direction of discharge flow.
