This paper
introduces a lot of situations about the Computational Fluid Dynamics (CFD) analysis
of backward facing step flows. The main point of this paper is incompressible
flow in a backward step, measured by drivers and Seegmiller experiments.



The researchers concluded that validation
parameters chosen for the study are the locations of the surface hydrostatic
pressure and the reattachment compression impact downstream of the step. The
surface static pressures predicted by WIND using a two-equation SST turbulence
model are shown below. This figure includes a comparison of earlier versions of
NPARC and WIND with experimental data. The WIND code slightly overestimates the
surface pressure drop from the free flow value to about 5% of the corner value
of the separation area (base pressure). This may be due to the fact that the
transition point is experimentally unknown and not accurately predicted by the
natural transition of the turbulence model. However, this over-forecasting
predicts the previous pressure drop closer to the experimental results than the
AEDC PARC, TUFF, and GASP codes using the Baldwin Lomax, KE, and Cebeci, and
Smith models, respectively. The rest of the forecast for WIND pressure is in
good agreement with the forecast pressure.
