![]() The main problem of computational fluid dynamics (CFD) is mesh generation for configurations with complex geometry specially with moving boundaries. Results indicate good agreements with those of available unstructured finite-volume flow solver (Uns2D) and other reference numerical data. The method is used for computation of flows around stationary and moving airfoils at subsonic and transonic flow conditions. An efficient central difference scheme with artificial dissipation terms is developed for both Cartesian grid and mesh-less zones. Last layer is used as virtual geometry for automatic generation of unstructured Cartesian grid around mesh-less zone. The mesh-less zone is created around the geometry by producing layers of nodes along normal direction vectors while Cartesian grid method is used elsewhere. Hybrid mesh-less and Cartesian grid method for moving boundary aerodynamic applicationsÄepartment of Aerospace Engineering, Amirkabir University of Technology, Tehran, ir*) AbstractĪ hybrid grid generation method that combines the computational efficiency of the Cartesian grid and the flexibility of the mesh-less strategy is developed for computation of compressible viscous flows with moving boundary applications.
