【 摘 要 】

In this paper a sub-parametric finite element method is used to find solution of Darcy Brinkman flow through a rectangular channel with one curved side using curved triangular elements. Finding the numerical solution for the flow through a irregular geometry involves a lot of computation time. In order to solve the flow problem with a much effective computational process, a finite element approach with curved triangular elements and with less number of degrees of freedom is employed. The demonstration of the effectiveness of the method is the objective of the paper. Results obtained are in good agreement with previous works done.
