The simple model simulation allows the validation of the computational scheme for future use in other projects with other geometries. This work presents the heat transfer problem in the cylinder heated from the central axis in an unsteady state, using the Finite Volume Method with a Half Control Volume. The radial temperature profile is shown for different Fourier numbers and different discretizations of the mesh, considering the Biot number and the inner radius pre-set.
