The surface is colored with pressure contours, and streamlines are shown to help visualize the flow. Aeroheating data on the front of the crew module helps validate the CFD results for flight conditions, and the CFD quantifies the effect of the sting on the wake flow and afterbody heating—allowing more accurate extrapolation of the wind tunnel data to flight conditions.
