The engineers are using CFD to improve the indoor ventilation with BIM HVACTool Software. The software played a crucial role in running the simulations.

The solver for this kind of project is: “buoyantSimpleFoam” with fvDOM radiation and humidity. Turbulence model can be used with k-Omega SST.

The moisture was not released directly at the mouth but can also be released as a source over the entire person. To do this, you can use the fvOption in the BIM HVACTool:

The background network can be set with the help of the BlockMesh. To do this, slide the slider either to the left or to the right:

Certain areas can be refined in the BIM HVACTool with a refinement box:

A jet nozzle can also be easily set using the boundary conditions:
