Give a Ejector working principle?

Question

Accepted Answer

An ejector works on the principle of converting pressure energy into velocity energy to create a vacuum.

An ejector consists of a motive fluid nozzle, a suction chamber, and a diffuser.
The motive fluid, usually a high-pressure gas or liquid, is forced through the nozzle, creating a high-velocity jet.
This high-velocity jet entrains and mixes with the suction fluid, which could be a gas or liquid at a lower pressure.
The mixing of the motive and suction fluids results in an increase in velocity and a decrease in pressure.
The mixture then enters the diffuser, where the velocity energy is converted back into pressure energy, creating a vacuum.
Ejectors are commonly used in various industries, such as oil and gas, chemical processing, and power generation.
For example, in a steam ejector system, high-pressure steam is used as the motive fluid to create a vacuum in a condenser.
Ejectors are efficient, reliable, and require no moving parts, making them suitable for demanding applications.
