Numerical simulation of liquid mass collision with a wall

摘要

Numerical simulation of high-speed liquid mass collision with dry or wetted rigid walls by the CIP-CUP method on dynamically adaptive Soroban grids is studied. A number of specially selected 1D and 2D test problems is used for validating the resolution of the main features of the collision separately. The results of their calculations are in good correlation with the corresponding analytical and numerical solutions. A problem of hemispherically-ended high-speed jet collision with a wall covered by a thin liquid layer is considered to illustrate the capabilities of the CIP-CUP/Soroban-grid approach to resolving the main features of the high-speed liquid collision together. Its numerical solution is in good agreement with the known similar results.
