主　　题：hybrid finite analysis method Navier-stokes laminar flow backwardfacing step. 

摘      要：A numerical solution for steady incompressible fluid flow over a two-dimensional backward-facing step for laminar condition was developed using a Hybrid Finite Analysis Method (HFAM). Attention is focused on obtaining accurate solution. The result of HFAM on the above problem is compared with other numerical solutions and experimental data to evaluate its numerical accuracy. It is concluded that some of the serious discrepancies that have occurred between prediction and observation at a large Reynolds number condition, and attributed in earlier studies to the inadequacy of two-dimensional model, had been due to the inaccuracy of the solution.
