Abstract

A finite integral transform technique is used to obtain an approximate solution to the Graetz problem with axial conduction and prescribed wall heat flux for an arbitrary velocity profile. Unlike the exact results of earlier works, this method requires minimal computational time yet compares excellently with the exact solutions for laminar flow of a Newtonian fluid for the entire range of Peclet numbers.
