Hi everyone!
I'm trying to use the Convective Velocity Option in a simple "brick" body - to get an unsteady moving temperature ditribution. Thermal conductivity is set to 1.0E-32 - so there is no conductive heat transfer. Initial temperature distribution has a sin-shape, so it's a smooth function. Non-zero convective velocity is set for X-axis. The only non-adiabatic boundary condition is on the short side, where temeprature is set to const. So I expect the temperature profile to move along the X-axis unchanged. But .. it is not happening - the ammplitude of the initial temperature distribution is decreasing. I've tried all the possible solver options (approximation orders, under-relaxation factors, time step etc) - but no luck. Any ideas - or is there something I am missing? |
