摘要：

A procedure is presented for obtaining a shape factor for transient heat conduction in arbitrary objects for which no analytical solution exists. Such a shape factor is the dominant parameter in the prediction of heat transfer processes. The procedure has been applied and compares favourably with other existing methods. Some data is given for transformation between the different parameters that are in use to describe shape or geometry, including those for an equivalent one-dimensional object.
