 August 2, 2007, 10:48 gear pump modeling - dynamic mesh creating #1 Salvatore Bocolo Guest   Posts: n/a Hi everybody. It seems I got serious troubles. For my final dissertation, I have to develope a cfd simulation (using Fluent) to investigate how a gear pump works. The problem is that I'm an absolute beginner in this matter, and at the moment I don't know anybody who can really help me. My goal is to determine the velocity field, the pressure field and the instantaneous flow rate. I have a lot of material (books, articles, original Fluent tutorials and pdf), but no clear criteria about how to use or select it to carry out an effective/efficient job. Therefore, I will be grateful to anybody who can give me significant suggestions. Thank you in advance.

Regarding motion, let's suppose n = 1500 rpm (costant). I'm talking about a common gear pump, with two identical spur gears, inlet and outlet ducts which simmetrically lead to and leave from the zone where the gears match. Moved fluid: oil. Thank you.
