Abstract:

The response surface method and method of lattice are combined for low-speed airfoil drag-reducing design,and the principles of response surface method and method of lattice are introduced in this paper.The advantages and disadvantages of the method are described.Flow field around airfoil are analyzed using the Navier-Stokes equations numerical simulation in which finite volume discretization is done and five-step RUNGE-KUTTA time stepping is carried out.The lift and drag are calculated by integrating of th...
