calculation of wall heat flux in CHT
Could you please help clarify the calculation of wall heat flux in CHT. The bc is a constant ambient temperature (100 deg C) and a given correlation of nucleate boiling as a function of heat flux (h = c*abs(Qwall)^0.671). For the heat fluxes at the inner wall and outer wall, how are they calculated and should I use 'wall heat flux' from the solver results for both? Is the constant T_ambient used here all the time for the calculation and given in the solver as the wall external temperature?
Many thanks! Fei
Send me your definition file, and maybe I can check out the prolem!
