The numerical results obtained by the present method have been compared with the exact one and also those obtained by earlier authors, and are found to be in very good agreement with each other. Further, it is shown that the numerical solutions satisfy the correct physical phenomena of the problem. (C) 2004 Elsevier Inc.
