Numerical dynamic simulation of the wig

摘要

For aircraft, low-level flying is highly dangerous and highly specialized. But WIGs (Wing In Ground; Ekranoplan) are designed to fly constantly and steadily in this mode. In this study, a three-dimensional Navior-Stokes analyzer based on control volume method is developed to simulate the complex flow field in a WIG. The TVD upwind method for solving the Navier-Stokes Equations has been developed to simulate these complex problems. For the spatial discretization, the least artificial viscous Roe's solver with high order Kappa MUSCL interpolation was used and, the second order explicit Hancock method was employed for time integration. According to the results of this research, this analyzer can indeed effectively modulate and simulate the aerodynamic characteristic of the WIG. The Position of the aerodynamic center is related to the Length between the boundary and WIG. The dynamic flowfield phenomena can be identified from the numerical results.
