Wave drag coefficient for a hypersonic flat plate is a dimensionless quantity that measures the ratio of the wave drag force to the dynamic pressure times the reference area of the plate. Wave drag is the drag due to shock waves that form on the surface of the plate when it moves at speeds higher than the speed of sound in the fluid. The wave drag coefficient depends on the shape, size, and angle of attack of the plate, as well as the Mach number and the properties of the fluid.Â
