SMAC method is adopted to solve Navier-Stokes equations,by using fifth-order WENO scheme and TVD R-Kscheme,LevelSet methods are used to capture moving interfaces with improved Ghost techniques.Some exam-ples,e.g.the incompressible inviscid flame interfaces of one and two dimensions and the rising-merging of oilbubbles in water,are computed and the comparison with the result of commercial CFD software Fluent has beendone.The rationality of LevelSet methods with Ghost technique in capturing moving interfaces with jump condi-tions is affirmed.It is shown that Level Set method can capture interfaces sharply without complicated recon-struction and can be easily programmed.
SMAC method is adopted to solve Navier-Stokes equations, by using fifth-order WENO scheme and TVD R-Kscheme, LevelSet methods are used to capture moving interfaces with improved Ghost techniques. Home exam-ples, eg the incompressible inviscid flame interfaces of one and two dimensions and the rising-merging of oilbubbles in water, are computed and the comparison with the result of commercial CFD software Fluent has bendone. The rationality of LevelSet methods with Ghost technique in capturing moving interfaces with jump condi- tions is affirmed. It is shown that Level Set method can capture interfaces sharply without complicated recon-struction and can be easily programmed.
