Low Reynolds number effects in single-room air flow.

The influence of the Reynolds number on low speed flow (essentially incompressible flow) is discussed. A first set of literature is reviewed to identify effects of low Reynolds number on flows in rooms. Methods of incorporating low-Reynolds-number effects in existing turbulence models are surveyed.

Review of active multitracer measurement methods.

The proposed task addresses the measurement methods using several tracer gases to measure the air flow rates between several zones of a building and between these zones and the outside air. If the building has N zones, there are N(N+1) unknown flowrates, which can be measured simultaneously using N different tracers. In so-called active methods the sampling of the atmospheres of the zones is made an active way, that is using either a mechanical pump or a manually actuated syringe or bag.
