Analytical Solution of The Laminar Boundary Layer Flow over Semi-Infinite Flat Plate: Variable Surface Temperature %K Homotopy Perturbation Method (HPM) %K Nonlinear differential equations %K Laminar thermal boundary layer %K Forced Convection %K Horizontal flat plate %K Variable surface temperature %R %X In this paper, the problem of forced convection over a horizontal flat plate under condition of variable plate temperature is presented and the homotopy perturbation method (HPM) is employed to compute an approximation to the solution of the system of nonlinear differential equations governing the problem. This paper provides good supplements to the existing literature and generalizes the previous investigation of the problem under condition of fixed plate surface temperature. It is shown that HPM is accurate and reliable with high acceleration in converging.   %U https://www.ije.ir/article_71860_85649ad730f4115b6e97752bfd4090a8.pdf
