Wall pressure interpolation for buoyant flow -- CFD Online Discussion Forums

April 27, 2010, 23:22	Wall pressure interpolation for buoyant flow	#1
khaiching New Member KaySee Join Date: Apr 2010 Posts: 5 Rep Power: 16	Dear CFD experts: I am developing an unstructured code and encounter a problem whereby the flow vector is pointing in/out near the wall when buoyancy model is on. I read from FLUENT manual that we can't set the normal pressure gradient at the wall = 0 when buoyant flow is simulated. Can anyone please guide me on the proper method to interpolate the wall pressure? Any references to share? I need the wall pressure in order for me to evaluate the cell pressure gradient near the wall. Please help. Thanks a lot.
