Herein, what is the function of a diffuser?

Diffusers are used on both all-air and air-water HVAC systems, as part of room air distribution subsystems, and serve several purposes: To deliver both conditioning and ventilating air. Evenly distribute the flow of air, in the desired directions. To enhance mixing of room air into the primary air being discharged.

Likewise, what is the difference between grille and diffuser? There is a quite significant difference between the grille and diffuser. A grille generally has straight openings, and it is installed at the opening of the duct system. Whereas, the diffuser has parallel angles plates which are moveable.

Subsequently, question is, what is the purpose of a ceiling diffuser?

About the Author: Ceiling diffusers are one of the few visible parts of an air conditioning system. Typically mounted in the ceiling of a home or commercial building, their purpose is to evenly distribute conditioned air throughout the room.

Why does supersonic flow accelerate in a diverging nozzle?

As the back pressure at the nozzle exit is made equal to the pressure required for the flow to fully expand isentropically, the flow accelerates throughout the diverging part of the nozzle and we get maximum velocity. Since the mass is always conserved, in order to achieve that, the flow has to accelerate itself.
