Approximate Methods of the Surface Mesh Deformation in Two-dimensional Case

Abstract

Numerical simulation of the surface ice accretion includes the work of various solvers that are performed iteratively and exchange data with each other. The calculation execution chain consists of the work of the gas-dynamic solver, the calculation of the liquid phase, the calculation of the thickness of the accreted ice on the surface grid and the rebuilding of the surface. After rebuilding is done, the modelling process goes to the next iteration in the gas-dynamic solver. Thus, the performance of a qualitative rebuilding of the surface computational grid taking into account the accumulated ice affects all further calculations. The article discusses approximate methods of rebuilding the surface mesh according to the ice accretion in each cell for the two-dimensional case and estimates their accuracy.
