According to the equation displayed below, I need to acquire temperature values (Tc) for calculating Q_loss.





Tc the (modeled) temperature inside the combustor, T∞ ambient temperature. Then Resistance is calculated as follows-
(2)





(3)


Pls tell me only how to acquire value of Tc.

If Tc means the temperature of a given cell C_T(c,t) is what you need.

cheers

Sorry for double post.. I have another doubt.i need to incorporate this line in the UDF. It is about removing the heat flux from a 2D plane, such that 3D results are obtianed.

Pls just tell me How to Subs for Heat flux.. Q = Q .+ (-2*(temp-300)/R);
just as Temperature is given by temp = C_T(c,t);

Pls reply ..
