- W2550602861 abstract "The development of CFD code with the use of parallel computing in conjunction with the multigrid and multiblock methods is presented for calculating an incompressible flow through a two-dimensional Tjunction. The finite volume method (FVM) is used to discretize the governing equations of the steady laminar flow. The QUICK scheme is applied for the convection terms while the central differencing scheme for the diffusion ones. The computation is carried out by using the CAMETA cluster, composed of 16 computers connected together with the Ethernet switch. The domain is decomposed into several blocks, each of which is assigned to one computing node (a computer with a single CPU). All nodes transfer the necessary data among themselves by means of message passing interface via the MPI library. In each block or node, the multigrid algorithm is performed as an accelerator of convergence rate. The FAS-MG-V cycle is adopted in this work. The results of this work show that the multiblock technique exhibits high potential to resolve a flow through the Tjunction having an irregular domain and, moreover, when incorporated with the parallel multigrid algorithm, the developed CFD code is much superior to the sequential algorithm using a single computer in terms of speed and convergence rate. In addition, the CFD code developed in this work gives more accurate results when employing the QUICK convection scheme." @default.
