First Trace for Irregular Shock Wave Process in Weak Mach Reflection
Referring to von Neumann's words, transition from a twoto a three-shock reflection configuration in the weak domain presents some very considerable theoretical difficulties. It nonetheless remains an observed fact that such a transition does indeed occur in the real world. This paper describes the novel experimental technique and the results which for the first time did yield a "footprint" that...
متن کاملThe Mach Reflection of Weak Shocks
We present numerical solutions of weak shock Mach reflections that contain a remarkably complex sequence of supersonic patches, triple points, and expansion fans immediately behind the leading triple point. This structure resolves the von Neumann triple point paradox of weak shock Mach reflection. During the second world war, von Neumann carried out an extensive study of shock reflection [5]. H...
متن کاملWeak-shock Reflection Factors
Ernst Mach (1838-1916) was the first to discover an irregular reflection phenomenon of shock waves, as is well known in our community. In fact, this occurred in 1875-three years earlier than usually assumed in the literature [1]. However, it is correct that Mach gave the physical interpretation of this phenomenon in 1878 [2]. Since Mach's discovery of an irregular shock reflection pattern some ...
متن کاملTransonic Solutions for the Mach Reflection of Weak Shocks
We present numerical solutions of the steady and unsteady transonic small disturbance equations that describe the Mach reflection of weak shock waves. The solutions contain a complex structure consisting of a sequence of triple points and tiny supersonic patches directly behind the leading triple point, formed by the reflection of weak shocks and expansion waves between the sonic line and the M...
متن کاملSelf-Similar Solutions for Weak Shock Reflection
We present numerical solutions of a two-dimensional Riemann problem for the unsteady transonic small disturbance equations that provides an asymptotic description of the Mach reflection of weak shock waves. We develop a new numerical scheme to solve the equations in selfsimilar coordinates and use local grid refinement to resolve the solution in the reflection region. The solutions contain a re...
