TRIANGULAR FIN TEMPERATURE DISTRIBUTION BY THE METHOD OF DIFFERENTIAL QUADRATURE

Abstract

Differential Quadrature Method (DQM) is a numerical technique for the solution of initial and
boundary value problems. This method has been succes sfully employed to solve a variety of
physical science and engineering problems. In this paper, the solution ofthe heat distribution in a triangular fin has been obtained by the Differential Quadrature Method. The numerical solution has been compared with the exact solution and it agrees very' well. The results show that unequally spaced mesh points yield stab le and accurate results. The numerical solution obtained by using equally spaced mesh points is less accurate and lead to instability once the number of grid points exceeds a critical value.
