“…Several analytical and semi-analytical methods have been proposed to solve the heat conduction problem through inhomogeneous fins including power series (Díez et al, 2009), the Adomian decomposition (Bhowmik et al, 2013); the homotopy (Moitsheki et al, 2015), the variation iterative and the differential transform methods (Joneidi et al, 2009). However, the differential transformation method (DTM) is well-known as an approximate analytical solution which provides more accurate results compared to other techniques such as the Adomian decomposition method and the variation iterative method (Salehi et al, 2012).…”
