G. Kosec, B. Šarler, Solution of phase change problems by collocation with local pressure correction

The melting/freezing of a pure substance is solved in primitive variables on a fixed grid with convection suppression, proportional to the amount of the solid fraction. The involved temperature, velocity and pressure fields are represented on overlapping sub-domains through collocation by using multiquadrics radial basis functions. The pressure-velocity coupling is calculated iteratively, with local pressure correction. 2D benchmark test is performed for two classes of materials: metals with Pr=0.02, Ste=0.01, Ra=2.51e4, 2.5e5, and organic materials with Pr=50, Ste=0.1, Ra=10e7, 10e8.
