  3. Abstract:
  4. The physical influence scheme has been successfully tested on quadrilateral grids performing noticeable features on collocated finite-volume approaches. This scheme exhibits excellent accuracy even utilizing coarse grid distributions to solve complex flow fields and solution domains. The main objective of this work is to extend the performance of a physical influence scheme to triangular grid applications using a coloacated finite-volume approach. A basic motivation behind this research is to construct more number of control volumes for a fixed number of grid nodes within a specified solution domain. In another words, a simple extension from quadrilateral to triangular grid can double the number of control volumes and reduce the size of each individual control volume. The reduction in control volume size would evidently improve the benefits of the scheme. To examine the outcome of this extension, the scheme is tested on cavity benchmark case which includes many major and minor vortices. The test case is solved with a variety of meshes and Reynolds numbers. The current results are compared with those of benchmark solutions and quadrilateral grids. © 2003 by M. Darbandi
