WHAT IS DIFFERENCES?

WHAT IS DIFFERENCES?

(OP)
Hello Gents ,

can anyone tell me whats is the defferences between Nozzel and diffuser and orifice ?
and for which porpuse should be used ?

thanks in advance

RE: WHAT IS DIFFERENCES?

Nozzle is a specially shaped outlet port, design to give a specific output pattern or spray.

Diffusers are used to decelerate the fluid or to control the velocity of the outlet flow.

An orifce is used to convert flow energy to pressure energy, or to control the fluid speed.

RE: WHAT IS DIFFERENCES?

HPost,
I can't tell the difference between a "nozzle" and a "diffuser" in your definitions. In common practice, a nozzle is "an entry/exit point from one process function to another". With no particular required configuration. Using that definition a "Diffuser nossle" limits the velocity of the outlet flow from one system to another. An "Orifice nozzle" (most people would call it a "restriction nozzle" is used to restrict the flow rate from one system to another by introducing a pressure drop.

I don't say that it's a statement of fact, it's a generalisation based on my own experience.
