• Heat transfer

• The temperature distribution on a cylinder wall

The temperature distribution inside a thick-wall cylinder is solved with its inner radius of 1m and its outer radius of 2m. The temperatures on the inner and outer walls are  and , respectively. The coefficient of thermal conductivity of the cylinder is 0.158  .

The heat conduction equation in polar coordinates is solved

with its boundary conditions:

Comparison between the solutions by use of FEM and analytical method:
