Hi, I have written a numerical code to solve the 1D heat equation in cyclindrical coordinates:
[tex]\frac{\partial T}{\partial t}=\kappa\left(\frac{\partial^{2}T}{\partial r^{2}}+\frac{1}{r}\frac{\partial T}{\partial r}\right)[/tex]
The problem I'm considering is a hollow cylinder in an infinite boundary, i.e. an underground tunnel surrounded by earth. All I want to do is verify that my code is working correctly so to do this I want to find the simplest analytical solution for 1D transient heat conduction using the simplest boundary condition, i.e. constant values. Now if this was in cartesian coordinates I would simply compare it with the solution for a semi infinite approximation. Unfortunately from my research I haven't found an equivalent for cyclindrical coordinates.
I may be missing some here so does anybody have ideas for a simple analytical solution? Thanks.
