摘要
采用有限体积法,结合半隐的Harten TVD格式和Baldwin Lomax代数湍流模型,求解了三维全N S方程,计算了超声速气流干扰流场,并与实验数据进行了比较,模拟清晰地捕捉到喷流附近复杂波系结构和旋涡结构,并且显示出了弹体表面受到喷流影响的区域,说明横向喷流干扰对弹体影响非常大。
The interaction flow with lateral jet in hypersonic flowfield was simulated numerically by solving three dimensional full NS equations, using finite volume method, half implied HartenTVD scheme and a algebraic BaldwinLomax model. The computation result was compared with the test data from foreign articles. The simulation captured the structures of shockwaves and eddies near the jet clearly, and showed the disturbed region to the missile. It proves that the jet has deep influence on the missile.
