About boundary contitions

November 9, 2007, 04:46

Hi, can anybody help me with my question: there are two big pools and pump transfering liquid between them. See http://www.jinr.ru/~akarak/toROT.png We solve (using STAR-CD) simple problem (pump without pools) instead of full one. Can anybody say, what boundary conditions are correct in this case?

Thanks.

I guess you need to find the pressure and flow rate of the liquid at the inlet of the pump based on the liquid level and inlet surface area, etc... and the outlet should be "flow split outlet".
