ABSTRACT	ESDU 75031 gives curves, derived from a correlation of experimental data, that enable the drag increment to be predicted due to l. a forward-facing step, ramp, or radiused step; 2. a rearward-facing step, ramp, or radiused step; and 3. a square-section ridge or a rectangular-section ridge (of height/width ratio 2) with or without corner radii, all normal to the flow direction on a flat plate.
