Computational Modeling and Simulation of Nonisothermal Free-surface Flow of a Liquid Jet Impinging on a Heated Surface

The study is aimed at formulating and validating the computational model for the nonisothermal two-phase flow with free-surfaces. The testing flow configuration consists of the liquid jet impacting on a heated wall generating simultaneous heat transfer from the wall surface. The interface capturing methodology implemented in the open-source software OpenFOAM® based on the volume-of-fluid (VOF) model in the framework of Computational Fluid Dynamics (CFD) is extended to incorporate heat transfer. The potential of the model is evaluated by contrasting the results of numerical simulations to the existing experimental and numerical results. The computational procedure based on the numerical model demonstrates good qualitative and quantitative predictive capabilities by reproducing correctly the studied flow and heat transfer characteristics.
