Cooling coil simulation in room

Hi guys
I am trying to model a chilled water cooling coil inside a room and find out about the effects of buoyancy and the humidity effects of a passive cooling coil, ie. no wind blowing across the coil, in a typical office room setting. For such a simulation, can someone tell me how can I simplify my modelling and what object should I use in order to simulate a chilled water cooling coil that has say, 7 deg C of chilled water supplied to the coil and ambient air of dry bulb and wet bulb temperature of 30 deg C and 25 deg C. There are not specific object templates that I can use to model this kind of cooling coil. Therefore, I think I may need some reliable assumptions on this scenario. I have been using FLAIR for simulation of air but I have no idea about simulating 2 fluids, ie. water and air, inside a single domain. Should I be going towards such approach? If so, is there any case study or tutorials that I should be looking at? |

I wouldn't simulate the air flow inside the room and the water inside the cooling coil. I always simplify the coiling coils by using an object with either a fix surface temperature or a fix heat flux (negative for a cooling coil).
