Numerical Simulation on Aerodynamic of The Wing in Ground Effect

摘要：

　　Aerodynamic characteristics of the wing NACA5312 in ground effect are investigated with the numerical simulation method.The N-S equations and the k-ε turbulence model are solved by the finite volume method in CFD software.This paper computes the flying states under different clearances,steam velocities and angles of attack.Compared with results under the unbounded flow,it studies the relations between the aerodynamic performances and the angles of attack,the steam velocity,and the relative heights.The aerodynamic performances include the lift coefficient,drag coefficient,and lift-drag ratio.
