GrabCAD
Diffuser in aerodynamics and hydrodynamics, the part of a channel or tube in which deceleration (expansion) of the flow and an increase in pressure takes place. At speeds not exceeding the speed of sound, the cross-sectional area of a diffuser increases in the direction of flow; at supersonic speeds, the area decreases. Diffusers are used in installations in which there is the movement of liquids or gases (water, air, gas, or oil pipelines, wind tunnels, and jet engines).
