  1. The numerical simulation of axisymmetric two - dimensional shock tube is studied, which has a conical convergent section, and its driving gas is the hot product of hydrogen oxygen detonation. finite volume tvd scheme is adopted and the mesh is local orthogonal. the primitive equations are euler s equations of multi - component flow. the new method of eliminating numerical oscillation at the interface of two materials is extended to two dimensions. the mechanical character of this shock tube is analyzed

  5. Finally, the two dimensional flow in the diffuser is calculated, the results show that the change of ma makes an effect to the performance of the diffuser. owing to the accretion of ma, the action of oblique shock waves and the boundary layer pricks up, the flow separates from the wall where the shock waves impinge on the boundary layer more quickly, the cluster of diamond shock waves becomes larger. moreover, by comparing the change of flow field under different structure parameter, it is found that the augment of length of constant area section alter the structure of fluid field little, a smaller area ratio and larger angle of compression section make the diffuser working better

    最後，針對擴壓器中的二維流場進行了數值模擬，結果表明馬赫數對擴壓器性能影響較大，隨著馬赫數的增大，擴壓器管道內激波-附面層干擾加劇，流動從附面層分離相應加劇，激波串數目增多;通過比較不同結構參數下的擴壓器內流場，發現等直段長度的變化幾乎沒有改變流場結構，只是對局部流場稍有影響，並且在其它參數不變的情況下，一定范圍內減小面積比a2 / a1和增大收縮角有利於擴壓器性能的提高。

  7. Then the explicit finite - volume method for the two - dimensional steady navier - stocks equations is studied. in order to prevent odd - even decoupling of the solution and oscillations near the shock waves, artificial dissipation is added. local time step, residue averaging, enthalpy damping and multi - grid method are used to accelerate the convergence during the five - step runge - kutta explicit time marching
