Secondorder explicit treatment of buoyancy term

maka · April 19, 2006, 09:03

I need to treat buoyancy term (beta*alpha*(T-T0)) on momentum equation with a second order scheme. I looked at fvSchemes dictionary and I could not find label that treat terms with no derivative. I notice that once I change that momentum equation and do some adjustment, the code run well. My question: how did the code treat the buoyancy term? Can I treat in second-order way (Adams-Bashforth for example)? Thanks.

best regards,
Maka

Excuse me， how can set Adams-Bashforth scheme in the fluent？
