Fluid Vs. Wall Temperature
Hi, I am modelling a fluid to solid heat transfer problem. The fluid is at a very high temperature (2100 K), but when I get the solution the solid wall in which it comes in contact with shows a very small increase in temperature (initial 300 K, final ~350 K). Also the material of the solid is copper. Does anybody have an idea what values I should play with to get some reasonable temperatures (exp. anlaysis gives me a wall temp. of around 650 K) I am using a Spart-allmaras turbulent solver for this 3D problem.
Re: Fluid Vs. Wall Temperature
grid resolution should be fine near the wall to accurately compute the gradients. check the y+ value and refine the grid if its greater than 5.
