Backward-facing step flow, which has many applications in engineering, was calculated by directly solving the Navier-Stokes equation, using the third-order accurate upwind finite-difference scheme. First of all, the influence of mesh size on the numerical results was studied by comparison with the exprimental results, and the appropriate mesh sizes were determined. Next, the calculated results with three different step ratios were compared with the experimental results by hot-wire anemometer and flow visualization. These results showed good agreement. The vortex development in the recirculation zone behind the step was clarified by the calculated results and the experimental results.
