Starting With A Detonation Wave
 
Hi OpenFOAM,

I am trying to simulate the combustion of an engine using OpenFOAM in a rotating cylinder using a detonation wave. The detonation wave is supposed to rotate around the cylinder; however, how do I start with the detonation wave then allow it to rotate? Additionally, how am I supposed to calculate Thrust and Mass Flow rate from injectors to calculate specific impulse?

My Mesh is below:

Any help would be appreciated!

Thanks,

I am also having a problem with doing a test run without the detonation wave, and I am getting the error

Cannot find patchField entry for Outlet

I am using reactingParcelFoam. I am trying to simulate a rotational detonation engine. The files are listed below here:

Any help?
