indoor ventilation
 
Hi,

I am going to study the vortex inside a my house(a fun project) with 2 rooms and kitchen and many window. The size of my room is about 10m*8m ( I am a poor guy) with ceiling about 2m.

Can anyone suggest what turbulent model, Heat transfer model that I should use?

Moreover, is there any quick method to guess the typical length scale and time scale for the vortex inside my house? For example, I will take the length scale as 2m as the ceiling height is 2m. And I will take the time scale as 60s. as a vortex with wind speed 0.1m/s moving inside my house will take about 60s to finish a single loop.

Is such kind of guess reasonable?

Thanks line
