Benchmark integral transform results for flow over a backward-facing step

Benchmark results for flow over a backward-facing step are obtained through the so-called generalized integral transform technique (GITT). This hybrid numerical-analytical approach is employed to handle the steady two-dimensional incompressible Navier-Stokes equations in streamfunction-only formulation. Numerical results with automatic global accuracy control are produced for different values of Reynolds number. Critical comparisons with previously reported experimental results are performed with excellent agreement. Also, a few different purely numerical approaches are validated, from a survey of the recent literature. Copyright (C) 1996 Elsevier Science Ltd
