Abstract: A procedure of generating 2-D unstructured grids with Delaunay triangulation is proposed. The grid generated can be used to computation of compressible flow in complex multiply-connected domains. A computer code for flow computations with the use of Euler equations on unstructured grid by finite volume method of cell-centred formulation is then developed. Some of the computation results are given.

Key words: unstructured grid, Euler equations, finite volume method
