How to cacluate the integral heat flux from an axisymetric geometry when the heat is entering into the surface and at the same time convection also occurs on the same surface

Please login with a confirmed email address before reporting spam

Hi
In my model heat is entering into the wall of the chamber from inner surface and at the same time some convection heat losses also at the same surface.When i calculate the total intgeral heat it gives me some negative number that mean heat is traveling against to the normal and that is the amount entring to the wall.But how to calculate the heat that is going to air by convection heat loss which is my target to find.
Please do guide.Hope some one will surely help me :)


Thank You in Advance
