A quadtree-based adaptive Cartesian grid generation and flow solver of Navier-Stokes equations were developed.The grid adaptation based on pressure or density gradient was performed and a gridless or meshless method based on the least-square fashion was used to treat the wall surface boundary condition,which is generally difficult to be handled for the common Cartesian grid.First,to validate the technique of grid adaptation,the flows over a cube were computed.Second,the flows over the cylinder were calculat...
