Higher Order Theory Across a Three-Dimensional Axially-Symmetrical Curved Shock Near the Stagnation Point

摘要: 本文建立了三维轴对称小曲率曲面击波驻点邻域的次级条件,其中包括热传导、粘性、击波结构的影响.这些击波条件是在局部击波斜率代替局部击波曲率前提下建立的.在Prandtl数等于3/4条件下,获得了驻点邻域附近的击波质通量、滞止焓、动量的切向分量和法向分量的修正公式的显形式.

Abstract: The next order conditions across a three-dimensional curved shock near stagnation point have been established, including the effects of heat conduction, viscosity and the shock structure. These shock conditions involve the local shock curvature in addition to its local inclination. Explicit results have been obtained for the correctional formulations in the mass flux across the shock, the stagnation enthalpy, the tangential component of velocity and the normal component of momentum flux.
