Based on the general LS method, an improved LS method for capturing compressible fluid with multi-interface interactions is given. This method can decrease the void region near the multi-interactions point, but not change the others. Both the LS equations capturing the material interface quality and the Eulerian conservative equations are solved by using a high resolution unspliting finite volume scheme, and fifth order WENO scheme for re-initialization level set equations. Some examination and application examples in capturing conjunct multi-fluid interfaces cases are simulated.
