On Mach Reflection and Strength of Reflected Shock

Abstract

The configuration of non-stationary Mach reflection has a conical similarity in time-space, since there is no fundamental time or space interval involved. This property is easily shown, and can be used to simplify the determination of various disturbance quantities. For this type of reflection the strength of the reflected shock depends on that of the incident shock and also on the deflection angle. To the first approximation, this reflected wave is a sonic front. Thus, the resulting boundary-value problem in linearized theory is relatively simple, and has been attacked by several investigators. The extension to second-order theory is discussed but is not carried out in detail. Based on the results obtained from linear theory, it is shown how the shock strength can actually be determined to the second order. The strength of this reflected shock is found to be of second order, and it vanishes at the triple point. (Author)
