| 摘要: |
| 本文用数值方法计算了不同高度滑移边界条件对钝体绕流流场特性的影响。采用化学非平衡粘性激波层控制方程，边界条件含壁面滑移、激波滑移和无滑移条件。计算结果表明，考虑滑移条件后，激波层较厚，激波处的电子数密度为一有限值。文中给出了计算结果，并与其它文献的结果作了比较。 |

| Abstract: |
| The numerical method is used for calculating the effects of slip boundary conditions on the viscous flows over blunt bodies at different altitude The nonequilibrium viscous shock-layer equations are used as the governing equations，the boundary conditions include shock-slip，wall-slip and no slip conditions. The numerical results show that the shock stand-off distance is thicker as slip boundary conditions are considered，and the value of electron number density behind the bow shock is not zero. The numerical resu1ts are pesented and compared with those from other methods. |
