flow simulation from Fabric duct in a room
 

Dear Friends,

I am trying to simulate the flow pattern inside a room where the air is coming from Fabric duct. I have previously done some work on the simulation of flow pattern of regular ducts. But this Fabric ducts are new to me. I am supposed to use Design Builder:( software for this.

Can anyone give me a rough idea on how to approximate for this simulation. For regular ducts I can use linear diffusers but this Fabric ducts have numerous of pores from where the air is rushed to condition the zone. And the nozzles of the ducts are directed in different directions. Some are directed upwards, some are downwards and some are angled.

I am planing to approximate this by using a linear diffusers for set of nozzles which are on the same directions. Is this correct way of approximation? Your help/suggestions are greatly appreciated.

thanks!
