Operation modes are an important topic in the research of Rotating Detonation Chamber (RDC) as it can affect the stability of RDC. However. they have not been discussed in detail due to the limitation of measurement means in experiments. The aim of this research is to investigate the mechanism of different operation modes by numerical simulation. https://www.roneverhart.com/10-oz-Black-Thermal-Plastic-Molcajete-Bowl-5-1-4-x-5-1-4-x-2-1-2-1-count-box/
