I have read through my references like ten time but I still don`t understand the concept of surge. Please someone give me a simple and understandable description of this phenomenon. I am so baffled help me out please. And what is a anti surge valve and it`s function?

A man in a restaurant orders item #1 on the menu; the waiter replies that they don’t have it.
The man orders item #2, and the waiter replies in the same manner.
The man finally responds, “Instead of my having to go through this litany, as a customer simply tell me what it is that you DO HAVE and be done with it!”

The same applies to your post in an analogous way. Why don’t you simply tell us all the references that you have read ten times and still don’t understand? Why should you make us go through the exercise, one-by-one, of finding out the references that you don’t understand? No one can succeed in explaining to you - in one thread or post – what centrifugal compressor surge is. It will take a reference. This has already been done - hundreds of times. No one is going to re-invent the definition of "surge".

So please help yourself out by doing some of the work: furnish the references and explain those details that you don’t understand. Chances are that you won’t understand us either if we don’t know before-hand what area you find difficult.

Hi,

Ok, this is what it looks like:

from compressor map you can see it happens when the flow rate falls a certain amount. and the definition says it happens when the flow rate exceeds from a certain point that compressor can not thrust the gas to outlet and a reverse flow happens and again after building up pressure in downstream of compressor the gas enters the compressor and this cycle happens till the surge valve opens and recycle some of the flow. I think as long as compressor can supply a certain amount of work to the gas then I should go with the definition not the map.
