註釋The flow field in a submerged inlet is investigated by theoretical, wind-tunnel, and visual-flow stuides. Equations are developed for the growth of the ramp-floor boundary layer for parallel, divergent, and convergent ramp walls; and a general equation is derived relating the boundary-layer pressure losses to the boundary-layer thickness. The formation of a vortex pair in the divergent-ramp inlet is discussed, and relationships are established between the vortex pressure losses and the geometry of the inlet.
