Stability and numerical analysis of the generalised time-fractional Cattaneo model for heat conduction in porous media.

Abstract

This work investigates the generalised time-fractional Cattaneo model. The homotopy perturbation transform technique is used to get the numerical solution of this model. The stability is analysed using the Lyapunov function, also the error analysis is discussed. Finally, the effectiveness of the proposed technique is illustrated by calculating the and error and comparing it with the existing techniques.
