Jet Engine case, initiating a detonation wave, and reactingParcelFoam errors

HRobertHS · March 11, 2017, 04:05

Hi OpenFOAM community,

I am trying to simulate a rotational detonation engine, except I am getting many errors and need help with starting the detonation wave.

CheckMesh output:

Also, I have two injectors, but neither work in injecting parcels. How am I supposed to create a subpatch for a detonation wave. I have looked online, but could not find any adequate explanations for myself. Finally, I was wondering how I can keep track of the thrust and mass flow rate to calculate specific impulse. I have a forces file in postprocessing and thought that that was needed. Any help would be appreciated, and I need to get this done very soon! The files can be downloaded here and is a relatively large case: https://www.dropbox.com/s/4kh5wkdsde...im.tar.gz?dl=0

I tried switching my thermoType model to

Code:

thermoType
{
	type	hePsiThermo;
	mixture	reactingMixture;
	transport	sutherland;
	thermo	econst;
	equationOfState	perfectGas;
	specie	specie;
	energy	sensibleInternalEnergy;
}

from

Code:

thermoType
{
	type	heRhoThermo;
	mixture	reactingMixture;
	transport	sutherland;
	thermo	janaf;
	equationOfState	perfectGas;
	specie	specie;
	energy	sensibleEnthalpy;
}

and a bunch of different types of thermoTypes, and could not obtain a result without an error.

I can't obtain any other thermoType to solve the problem besides the original.... Should I also start from a higher initial temperature and make T_react above 0?

Please help.... I tried creating a new mesh and forming a patch from a partition in SALOME. The detonation patch doesn't register and OpenFOAM creates a default patch for it along with many other cells. I tried changing some parameters around, but still get the same thing... I then tried to use simFlow and obtain this:
