| Abstract: | Under the conservative scheme,flux components are reconstructed with the component by component versions.Then the quasi-linear systems are solved by the multiple WENO reconstruction based on the 1st order up wind scheme.The level set equation is used to capture the interface movement.Finally the two algorithms are applied to simulate the muti-component fluid flow.Satisfied numerical results have been obtained. |
