Numerical solution for the hyperbolic heat conduction problems in the radial-spherical coordinate system using a hybrid Green's function method

The hyperbolic heat conduction problems in the radial-spherical coordinate system are investigated by the hybrid Green's function method. The present method combines the Laplace transform for the time domain, Green's function for the space domain and ɛ-algorithm acceleration method for fast convergence of the series solution. Three different examples problems have been analyzed by the present method. It is found that the present method does not exhibit numerical oscillations at the wave front and the numerical solutions are stable.
