Development and application of a specialized parallel code for numerical simulation of unsteady turbulent freesurface flows

Abstract

 Computational method for free-surface flow modeling is presented with an emphasis on original developments aimed at improvement of solution accuracy and robustness of the VOF (Volume-Of-Fluid) method in cases of extra computational complexity. The computational techniques developed have been implemented in a specialized 3D unstructured-grid parallel code. Parallelization of computations is based on the “domain decomposition” technique. Examples of the code application to modeling of 2D and 3D unsteady turbulent flows interacting with obstacles of different shapes are presented. Computational results are compared with experimental data.
