摘要：

A hybrid method is used to investigate the transient response of annular fins of various shapes subjected to constant base temperatures. The time-dependent terms in the governing equations are removed by using the Laplace transformation, and the integral method is used to solve the transformed boundary value problem. The inverse Laplace transform is calculated by applying the Fourier series technique with modification. It is shown that the Blot number and geometrical parameters have pronounced effect on the transient heat transfer in annular fins. (C) 1998 Elsevier Science Ltd.
