The finite difference formula was derived for the temperature of a finite cylinder. This method of numerical analysis for two-dimensional steady-state heat conduction problems with any combination of temperature, gradient and convection boundary conditions is presented. Excellent agreement with the experimental result is illustrated for a finite cylinder.

The temperature distributions of a spherical shell due to a moving point heat source were studied by analytical approach and checked by experiment. A spherical shell had two point heat sinks and physical properties of spherical shell were assumed to be uniform and the heat transfer coefficients were assumed to be zero. The heat transfer equation for the systems was solved by a finite difference method for the quasi-steady state condition. Temperature profiles of the spherical shell were measured by thermocouples and were compared with the calculated profiles. Agreement of the analytical and experimental results was good.

The temperature distributions of a spherical shell due to a point heat source were studied by analytical approach and checked by experiment. The temperature of a point source varied with time as T=(τ)/(a+bτ). Physical properties of spherical shell and the heat transfer coefficient of outer surface were assumed to be uniform. The heat transfer equation for the system was solved by a finite difference method for the unsteady state condition. Temperature profiles of the spherical shell were measured by thermocouples and were compared with the calculated profiles. Agreement of the analytical and experimental results was good.
