a prandtl–meyer compression is the opposite phenomenon to a prandtl–meyer expansion. if the flow is gradually turned through an angle of δ, a compression fan can be formed. this fan is a series of mach waves that eventually coalesce into an oblique shock. because the flow is defined by an isentropic region (flow that t...

prandtl–meyer fans can be expressed as both compression and expansion fans. prandtl–meyer fans also cross a boundary layer (i.e. flowing and solid) which reacts in different changes as well. when a shock wave hits a solid surface the resulting fan returns as one from the opposite family while when one hits a free bound...

oblique shock waves are similar to normal shock waves, but they occur at angles less than 90° with the direction of flow. when a disturbance is introduced to the flow at a nonzero angle (δ), the flow must respond to the changing boundary conditions. thus an oblique shock is formed, resulting in a change in the directio...
