Abstract : This report presents finite-difference (forward) heat transfer equations applicable to transient, radial heat flow in spheres and cylinders and applicable to transient, one-dimensional heat flow in flat plates. By minor manipulations, a single heat transfer procedure can be utilized easily to determine the transient heat flow in all three basic structure configurations. For each skin configuration the accuracy of the finite-difference procedure, compared with exact analytical methods, depends on optimum selection of the calculation time increment and the incremental distance between temperature nodes in relation to the material thermal properties and on the closeness of the approximate temperature gradients to the true gradients.
