TY - JOUR TI - Reduced differential transform and variational iteration methods for 3-D diffusion model in fractal heat transfer within local fractional operators AU - Jafari Hossein AU - Jassim Hassan Kamil AU - Vahidi Javad JN - Thermal Science PY - 2018 VL - 22 IS - 11 SP - 301 EP - 307 PT - Article AB - The analytical solutions of the 3-D diffusion equation in fractal heat transfer is found. The reduced differential transform and variational iteration methods are considered in the local fractional operator sense. In order to show the power and robustness of the proposed techniques, illustrative example is presented. The results reveal that the presented methods is very effective and simple, and can be used for other problems in mathematical physics.
