BOUNDARY LAYER COMPUTATIONS ON CFD GRIDS

摘要

System and method for computing boundary layer properties are disclosed. In one embodiment, a first boundary layer cell that is substantially close to a wall of a structure is selected. A recursive function is then launched for each cell adjacent and around the selected first boundary layer cell to determine a cell having a highest dot product with the normal of the first boundary layer cell. The cell having the highest dot product with the first cell is declared as the second boundary layer cell. The declared cell is selected as the second boundary layer cell. The above steps of selecting, launching and declaring are repeated until a desired number of layers in the boundary layer are completed. The boundary layer properties associated with each selected boundary layer is computed using CFD analysis.

1. A method of computing boundary layer properties, comprising:
selecting a first boundary layer cell, that is substantially close to a wall of a structure; launching a recursive function for each cell that is adjacent to and around the selected first boundary layer cell to determine a cell having a highest dot product with the normal of the first boundary layer cell; declaring the cell having the highest dot product with the first cell as the second boundary layer cell; selecting the declared second boundary layer cell; repeating the above steps of selecting, launching and declaring until a desired number of layers in the boundary layer are completed; and computing the boundary layer properties associated with each selected boundary layer using CFD analysis.
