| Abstract: | Numerical investigation of the flow around delta wing at high-angle-of-attack is presented in this paper, under the consideration for characteristics of flow at large incidences and possible difficulties in numerical simulation. Effects of computational grid on numerical results are discussed in details. Experiences are accumulated for the numerical simulation of flow past complex configurations at high-alpha. |
