What is pressure recovery?

Pressure recovery refers to the process in which fluid pressure is restored after a drop caused by factors such as friction, turbulence, or expansion in a flow system. This phenomenon typically occurs in ducted flows, where the fluid experiences a reduction in velocity and an increase in pressure as it transitions from a high-speed region to a more stable flow area. Effective design of conduits, nozzles, and diffusers can enhance pressure recovery, improving overall system efficiency.
