Hi

I am trying to solve a Heat Transfer problem (of transient conduction in a 2D annulus of material with convective boundary conditions). I currently have a fixed heat transfer coefficient, but in reality this varies with surface temperature.

I am using the PDEsolve meothod to solve the equation. Is there a way of linking the temperature at the end of each time step into an equation to calculate h.

I am a Maple/programming...

Hi

I have been using the pdesolve command to solve the heat conduction equation in an infinitely long cylinder, but now I need to incorporate the convection that occurs at the end surfaces, in the case of a short cylinder.

The following is the code I have been using:

>> PDE := diff(Theta(r, t), r, r)+(diff(Theta(r, t), r))/r = (diff(Theta(r, t), t))/alpha;

>> pdsolve(PDE);

I have tried to add...
