Reacting flows

Description : 3D simulation of RDE with unstructured mesh using AVBP software.
Simulation of the plenum in order to quantify the effect of the reverse flow.

 

Description : 3D simulation of RDE with unstructured mesh using AVBP software.
Here, a slice perpendicular to the detonation direction.
We can see a shock wave going back into the plenum.

 

Description : 3D simulation of RDE with unstructured mesh using AVBP software.
Top view of the engine.
The slices are at differents level in the combustion chamber.
There are the main shock wave due to the detonation which is moving, and behind secondary shocks.
