The Poisson solver based on a modified Successive Over-Relaxation (SOR) method is implemented on an array of 16 transputers (T805), and it is applied to solve the incompressible Navier-Stokes equations in terms of the vorticity-stream function formulation. The method of lines approach using a rational Runge-Kuta time integration scheme is adopted to solve the vorticity transport equation. As a parallelizing strategy, the domain decomposition technique is used to solve the partial differential equation on a structured grid. The result of the parallelized Poisson solver for 129 x 129 grid points gives high speedup of 15.7 and efficiency of 0.98 of computations on 16 Processor Element (PE)s. In the computation of the incompressible Navier-Stokes equations, an almost linear speedup of approximately 15.96 is gained and corresponding efficiency 0.998 is obtained through the present implementation of the parallel algorithm for 16 transputers.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
