Book Description
~~~~ INTRODUCTION 1. - The problem for analysis and requirements 2. - Results 3. - Comparison of computer times 4. - Conclusion. INTRODUCTION In 1981 it appeared to the organizers that a workshop to compare codes to solve the Navier -Stokes equations would be of great interest to the community of numerical analysts and users working on CFD (Computer fluid Dynamics}. A test problem would have to be selected with the following features : 1. it should be suited for all known methods (finite differences, finite elements, spectral ... ) thus the geometry should be simple. 2. it should be simple so that scientists with small computer facilities can test it and the gradients in the flow should be reasonable in size so that algo rithms don't blow up with a limited number of points and iterations. In practice one would have to select a stationary flow at moderate Reynolds number. 3. it should be a real flow to allow experimental ~asurements. The simplest problem used previously was the cavity flow problem ; however the singularity of the data at the boundary (point A and B on figure 1} makes it difficult for the Finite Element and Spectral methods ; furthermore it is not such an easy experiment to set up. A B .... u = 2 Flow around a cylinder, although most interesting of all, is too difficult because it is unbounded (many grid points) and very quickly unsteady {Re ~30).

Book Description
The steady, two-dimensional flow of an incompressible fluid over a backward-facing step is computed by a finite difference procedure. The flow depends upon the Reynolds number, Re, based on the inlet flow conditions, and on the dimensionless step height, s. Spatially resolved, accurate solutions are obtained for a range of s for Reynolds numbers as high as 350. The primary flow feature is a steady separated region immediately in back of the step. Additionally, a secondary separated vortex can appear on the top, straight wall of the channel. A region is delineated in the (s, Re) plane where laminar separation occurs on the top surface. It is concluded that there is no flow reversal on the top surface if Re is less than about 200, regardless of the step height s. The occurrence of this secondary vortex is associated with laminar separation of the top boundary layer produced by an adverse pressure gradient along the top of the channel.
