TLDR
In this article, the authors consider the supersonic flow inside a channel that suddenly turns and generate a centered expansion wave and an oblique shock wave at the expansive and compressive corners.Abstract:
We consider the supersonic flow inside a channel that suddenly turns. For the flow to negociate this sudden turn, a centered expansion wave and an oblique shock wave are generated at the expansive and compressive corners. We study the interaction between an oblique shock and a centered fan, the subsequent interactions of the reflected shock and reflected expansion waves are not considered hereread more

Size and shape of shock waves and slipline for Mach reflection in steady flow
Chen-Yuan Bai,Zi-Niu Wu +1 more
TL;DR: In this article, the shape of the curved slipline and reflected shock wave were derived for steady supersonic flow, and it was found that, due to transmitted expansion waves from the expansion fan, the curve of the slippine has a slope discontinuity at the turning point, i.e., the intersection point of the curve and the leading characteristics of the transmitted expansion wave.

Shock-wave/expansion-wave interactions and the transition between regular and Mach reflection
TL;DR: In this paper, the authors present numerical simulations for the interaction of an expansion wave with an incident shock wave of the opposite family, the specific aim being to study the resultant reflection of the now-perturbed shock wave from a solid surface.

An analytical model for asymmetric Mach reflection configuration in steady flows
Shobhan Roy,Rajesh Gopalapillai +1 more
TL;DR: In this article, an analytical model for the configuration of Mach reflection due to the interaction of two-dimensional steady supersonic flow over asymmetric wedges is presented, where the subsonic pocket downstream of the Mach stem is taken to be oriented along an average inclination, based on the streamline deflections by the mach stem at the triple points.

Numerical solutions of time-dependent incompressible Navier-Stokes equations using an integro-differential formulation
J.C. Wu,J.F. Thompson +1 more
TL;DR: In this article, a numerical method for the solution of the Navier-Stokes equations is developed using an integro-differential formulation of the equations, which permits the actual computation to be confined to the viscous region of the flow and offers a drastic reduction in the number of data points required in the numerical procedure.
