摘要
The incompressible N-S equations are solved by using a pseudo-compressibility method. Computation is made for both 60°and 70°sharp edged delta wings. Thepredictions for position and angle attack of vortex breakdown are investigated. The effectof the leading edge sweep angle on vortex breakdown is also discussed. Numerical resultsshow that the present method is an effective tool for investigation of vortex breakdown atlow speed.
