[Anupam]

Hello Respected foamers,

I am new on the forum and I will introduce myself.
My name is Anupam and I am a student working in fraunhofer in germany in HVAC domain.

I am working on my dissertation. I want to have visualisation of fresh air and old air in a room with openfoam tool. The goal is to study the behaviour of both air in the room.

1) First step is to create a 2D geometry of a room. This step is done. The
blockmeshdict file contains a box with one inlet, one outlet and rest walls.

2) Since, waste_air already exists in the room and the fresh_air enters the room through inlet and pushes it out through the outlet. I defined a fresh_air inlet velocity.

3) I used rhoReactingBuoyantFoam solver. Is this the right one for modelling fresh_air and waste_air flows ?

4) The fresh_air and waste_air flow appears good. But there is, something about the air velocities (U) which does not seem correct. I don't know what is wrong there. Can anyone please look into the files and see if there is any problem here? I am not so good in interpretation of results.

Regards,
Anupam
