文摘To simulate numerically the flow past a cylinder, the authors use a mixing method of FEM and FDM for solving the non-steady Navier-Stokes equations in two-dimension. The mesh of computing domain which includes a cylinder with complicated section is generated by composite technique. The results about the flow pattern around the cylinder, pressure distribution on the surface of cylinder and the coefficient of lift and drag agree well with experiment data.
