  • Vorticity-refinement based numerical method for simulating aircraft wing-tip vortex flows
    Patent number: 9390205
    Abstract: The present invention relates a numerical method to simulate the incompressible wing-tip vortex flows. This method is called Vorticity-Refinement, which refines the added vorticity as two different forms of force multiplied by two different factors to counteract the numerical diffusions in the numerical solutions by utilizing the high-order spatial discretization and improving the stability and convergence of the governing equations for incompressible flows.

  • Numerical method for solving an inverse problem in subsonic flows
    Patent number: 9384169
    Abstract: It is a numerical method for solving an inverse problem about the shape design of aerodynamic body in inviscid subsonic flows. This method transfers the original Euler equations into the stream-function plane, where it solves the Riemann problem across the streamline presenting the solid-wall and obtains the geometry of the solid-wall concurrently.
