CE/SE method applied to flows around 2D airfoil

  • A numerical scheme for solving Euler equations was conducted to investigate inviscid flows around 2D airfoil according to space-time conservation element and solution element (CE/SE) method. Courant number insensitive scheme (CNIS) used to avoid the contaminations of numerical dissipation induced by very small Courant number, improved the accuracy combining with local time-stepping(LTS) method that canceled the disparity in Courant number at non-uniform meshes. Two dimensional numerical simulations for NACA0012 airfoil were implemented. The results show that it is in agreement with the published data by AGARD, which will provide sufficient preparations for the application of CE/SE method to airfoil at more fields.
