Internal structure of a shock can exhibit linear instability



The video presentation, made for the AIAA SciTech 2021 conference, summarizes the highlights of the Mach 7 nitrogen flow over a double-wedge at input conditions corresponding to 59 km altitude.


One of the key takeaways from this talk is that kinetically resolved internal structure of a shock-wave exhibits linear instability.


This simulation required approximately 800k node-hours to simulate up to 160 flow-times. A flow time is defined as the time it takes for the flow to traverse a length of the separation bubble in the base flow at a freestream velocity. This work would not have been possible without the computational resources I received to use the following supercomputers.

TACC's FRONTERA (an LRAC award)

TACC's STAMPEDE2 through XSEDE

NSF's BLUEWATERS

I have been growing different types of mosses at home. It's really easy and fun.
