Hi,
I'm trying to solve a square cavity (1x1m) with natural convection heat transfer. Both top and bottom are insulated, left surface is T=330K and right surface at T=300K. The Boussinesq approximation is use for density. Thermophysical properties: rho=1.127 Cp=1007 mu=1.9114e-5 k=0.0271 Beta=0.006092 gravity= -9.81 I already tried to start the simulation with default solution methods and after a few iterations chance momentum and velocity values in order to achieve convergence of the result, but it doesn't worked. Any other helpful suggestion? Thanks in advanced |
