Flow of an centrifugal pump

Sammy Redshaw Jun 24, 2011 4:51 PM

Hi I am new to to flow simulation, I had my VAR demo flow works on my product. What I want to know is why you have to draw a sketch revolve arond the impeller part. is this to simplify the model or to tell the mesh the impeller is rotating? Is there any way of getting a screen shot of the centrafugal pump tutorial in flow works so that i cna explain it clearly to my collegue who have very limited unstanding of FEA, they thought is would be a case of clicking on components and telling flow works this part revolves and this part is a wall or static.

That is to specify the rotating region. We keep the impeller stationary but apply rotation speed to the RR.

    As far as I know, the area around the impeller is of more interest rather than impeller itself in flow simulation. That is area where initial movement of fluid takes places. Also the margin around the impeller should be taken with a great care i.e it should be too much or too low.
