Abstract
Abstract In this paper, the temperature distribution in a convective radial fins is analyzed through a fractional order energy balance equation with the consideration of internal heat generation and temperature dependent thermal conductivity. Adomian decomposition Sumudu transform method is used to study the influence of temperature distribution and the efficiency of radial fins for different values of thermal conductivity and to determine the role of thermal conductivity, thermo-geometric fin parameter as well as fractional order values in finding the temperature distribution and the fin efficiency of the convective radial fins. Finally, the efficiency of this proposed method has been studied by comparing the obtained results with the classical order results obtained by using numerical method and Variational Iteration Method (Coskun and Atay, 2007).

Summary
Extended surfaces, called ns, are used to elevate the heat transfer rate involving a hot body and its surrounding environment and can be modelled in various geometrical shapes such as rectangular, trapezoidal, triangular, and cylindrical. Aziz and Torabi [2] considered the simultaneous variation of surface emissivity with heat transfer coe cient, temperature and thermal conductivity and studied the convective–radiative ns numerically. They [3] employed DTM to analyze the e ciency of a T-shape n of combined radiation, convection and with thermal performance. Patel and Meher [8, 9], introduced ADSTM which is a combination of Adomian Decomposition Method [10] and Sumudu transform method They studied temperature distribution and n e ciency in convective n with internal heat generation and porous n with di erent fractional order values. They [12] carried out induced magnetic eld e ect on stagnation ow of a TiO -Cu/water hybrid nano uid over a stretching sheet Ghadikolaei et al [13] used AGM to analyze unsteady MHD Eyring-Powell squeezing ow in stretching channel with considering Joule heating and thermal radiation effect
