摘　　要：In this paper, we present a simplified third-order weighted ENO finite volume method on unstructured triangular mesh. The third-order TVD Runge-Kutta time diswcretization is used. A weighted quadratic reconstruction is constructed on every triangular mesh. Preliminary encouraging numerical experiment is given.In this paper, we present a simplified third-order weighted ENO finite volume method on unstructured triangular mesh.
