New techniques for Multi-block Hybrid Meshes with Non-uniform cells on Interface and appropriate numerical schemes

New Techniques for Multi-block Hybrid Meshes with Non-uniform cells on Interface and appropriate numerical schemes is discussed. In allusion to limitations of patched grids that the cells in different sub-domains must be uniform on interface, a new method for hybrid grid decomposition with non uniform cells(nodes) on interface is developed. In terms of theoretical analysis, the mesh generations of sub-domains are independent with each other, and this property will reduce greatly the difficulties in grid generation of complex problems, such as three-dimensional flows. Simultaneity, numerical schemes based on Jameson´s method is developed to match the new grid definition. Numerical results of inviscid flow around NACA0012 airfoil are obtained, and compared with those in references.
