UDF which defines the surfaces temperature as a function of the surface heat flux?
Is there any Ansys Fluent UDF which defines the surfaces temperature as a function of the surface heat flux?
I want to model a radiation adiabatic wall condition for hypersonic flow (energy balance). This way I define a variable temperature wall boundary condition that implies a dynamic evolution of the wall temperature governed by a surface energy balance at the wall interface.
q_out = radiativ heat flux from wall to gas = e*sigma*T^4 (Stefan Boltzmann Equation)
For this I need to access the Heat Flux from wall to gas which is, I think, defined in Fluent as BOUNDARY_HEAT_FLUX(f,t)
