TY - JOUR TI - Modified variational iteration method for straight fins with temperature dependent thermal conductivity AU - Inc Mustafa AU - Khan Hasib AU - Baleanu Dumitru AU - Khan Aziz JN - Thermal Science PY - 2018 VL - 22 IS - 11 SP - 229 EP - 236 PT - Article AB - The modified variational iteration method (MVIM) has been used to calculate the efficiency of straight fins with temperature dependent thermal conductivity. The obtained results are compared with homotopy analysis method (HAM), homotopy perturbation method (HPM), and Adomian decomposition method (ADM). It is used w ≠ 0 auxiliary parameter to keep under control convergence region of solution series in MVIM. As a result, although MVIM and HAM give results close to each other; HPM and ADM give divergent results from analytical solution.
