In the context of the interaction between a moving plane shock wave and aninclined wall (wedge), it is possible to distinguish four distinct shockreflection configurations. These shock wave reflections, which depend on thecharacteristics of the incident shock wave and the geometry of the surface thatit interacts with, are (i) regular reflection (RR), (ii) simple Mach reflection(SMR), (iii) transition Mach reflection (TMR), and (iv) double Mach reflection(DMR). The impact of these shock reflections on flow properties can besignificant so understanding them is important when predicting the behavior ofshock waves in more complex flow configurations. Previous research works haveexplored the referred shock reflections through both numerical and experimentalapproaches, employing various gases and different flow and geometricalconfigurations. The present study involves the use of a high-fidelitycomputational fluid dynamics (CFD) tool, known as PeleC, which is acompressible solver based on AMReX specifically designed to handle complex flowconfigurations. Accordingly, by solving the time-dependent Euler equations forvarious 2D flow configurations, this work studies shock wave reflectionsaccounting for four different Mach-based operating conditions and compares andanalyzes the resulting density profiles on the wedge wall with experimentaldata. To strike a balance between model accuracy and computational efficiency,adaptive mesh refinement (AMR) is incorporated, and a mesh independence studyis performed by varying the number of AMR levels. The results of this studydemonstrate the capabilities of the CFD tool employed as it accurately predictsthe sensitivity of wave characteristics to different operating conditions.
