Is it possible to remove the carrier phase completely for reactingParcelFoam and just have inert air while particle interaction causes temperature variations in the domain?
I want to try modeling something similar to heat transfer in a packed bed of particles.

Thanks

Hey Aishwarya,
I can only give you some ideas on how I would try to mimic your problem. From an implementation point of view it is not possible to "remove" the carrier. The particle mass and heat transfer equations include convective parts which are depending on the carrier velocity. In order to remove this you will have to set the velocity to zero. What you are then solving is a basic heat conduction equation with source terms due to the particle phase. My suggestion is to throw away the equations for U and p and to only solve the energy equation while keeping the carrier density constant. Alternatively, set the velocity to zero and remove the momentum exchange between particles and carrier.

Cheers
RP
