Hello everybody on forum

Can someone clarify why CFD analysis is required at intake side (suction side ) while designing large pumps,since small types of pump generally not required CFD analysis for design at suction side.

(1). I guess the smaller pumps cost less, so you don't want to spend a lot of time there. (2). A larger one will cost much more in casting and machining, so, there are room to do analysis and design to make sure that everything is all right. (3). A larger one sometimes is custom made. So, it is likely to do analysis. (4). CFD analysis of pumps is still relatively new, and it is rarely done in most cases.(it is still very difficult, although not impossible.)

I have worked on the design of internal-external gear pumps for automotive applications (Gerotors, crescents, etc). Occasionally you see someone doing a very nice and computationally expensive moving mesh simulation to check out the inlet port design.

The reason being that above a certain speed the inlet pressure will drop sufficiently to allow cavitation. This results in very noisy and inefficient operation.

Hope this helps.
