This boundary condition can operate in the following two modes: Mode#1Specify the heat fluxq −kTp–Tb|d|=q+qr(2) *k: thermal conductivity *qr: radiative heat flux *Tb: temperature on the boundary Mode#2Specify the heat transfer coefficienthand the ambient temperatureTa(Fig. 1) −kTp...
hi fomers, has anybody tried to apply a convective heat transfer boundary condition with the following constraints, 1) prescribe heat transfer coefficient(h) and free stream temperature (Tinf) 2) h & Tinf are functions of time, space and local wall temperature 3) local wall temperature of pre...

The heat flux also gave the same amount symmetrically as Qf=-Qs, and it can be expressed as kfdTfdn=-ksdTsdn if the radiant energy condition is neglected. In CFD analysis, the number and shape of meshes are very important, as well as the skill of the person performing the analysis. ...
