The reflection of a converging cylindrical shock over a double curved wedge was investigated experimentally and numerically. The double curved wedge was specially designed to ensure that the wedge angle only changes at the corner during the cylindrical shock reflection. Seven different reflection processes existing in the planar case were reproduced in the converging case. The sudden variation of the wedge angle alters the strength of the disturbance propagating along the converging shock. Depending upon the type of the flow-induced pressure waves, which dominate the type of the wave behind the reflection over the second wedge, the propagation of the disturbance is either promoted or restrained. Comparison of the lengths of the disturbed shock front between the single wedge reflection and the double wedge reflection indicates that the history of the reflection over the first wedge would affect the reflection over the second wedge. Provided that the Mach reflection over the second wedge is fully developed, it approaches the Mach reflection of an identical shock over a single wedge with the same wedge angle as the second wedge. Relative to the planar case, the convex curved surface in the converging case promotes the disturbance propagation and increases the trajectory angle of the triple point.

通过实验和数值研究了会聚圆柱激波在双曲楔上的反射。双曲楔专门设计用于确保在圆柱冲击反射过程中楔角仅在拐角处发生变化。在会聚的情况下再现了平面情况下存在的七种不同的反射过程。楔角的突然变化改变了沿着会聚激波传播的扰动强度。根据流动引起的压力波的类型，在第二个楔子上的反射背后的波的类型占主导地位，扰动的传播要么被促进，要么被抑制。单楔反射和双楔反射受扰激波前缘长度的比较表明，第一楔反射的历史会影响第二楔反射。假设在第二个楔子上的马赫反射完全展开，它接近与第二个楔子具有相同楔角的单个楔子上的相同激波的马赫反射。相对于平面情况，会聚情况下的凸曲面促进了扰动传播并增加了三相点的轨迹角。它在一个楔角与第二个楔子相同的楔子上接近相同激波的马赫反射。相对于平面情况，会聚情况下的凸曲面促进了扰动传播并增加了三相点的轨迹角。它在一个楔角与第二个楔子相同的楔子上接近相同激波的马赫反射。相对于平面情况，会聚情况下的凸曲面促进了扰动传播并增加了三相点的轨迹角。
