Disturbances from the surroundind environment and boundary conditions can influence very much the flow pattern , particles concentration and temperature distribution in a room.This report confirms the importance of working with measurements and simulations in parallel. Simulations of indoor air quality need to be validated . Guidelines on how to combine results are discussed in the paper.

Experiments were carried out in a scaled test room equipped with 9 vortex inlets uniformly distributed, exhaust outlets near the floor and 64 mannequins to simulate cooling loads. The study describes the air flow pattern observed and the relationship between the air velocity and the cooling load per m2 for mixed flow.

The paper presents the results of the measurement of turbulence intensity in jets issued into enclosures of different size. The test results confirm the relation between the velocity distribution coefficient and turbulence parameters.

The paper presents the results of experimental tests : the enclosure size and background turbulence in the surroundings of the jet have an influence on the air velocity distribution in axisymmetric jets

Measurements and CFD simulations are compared for 4 different ventilation systems using the air change index and a new ventilation parameter. It is shown the advantage of impinging jets

Experioments has been conducted with a ice thermal storage and a ceiling plenum. This ductless air supply system can be an alternative to the use of chilled water tubes. This system supplies air to the ceiling plenum chamber by mixing return air and low temperature air.

In this paper, 2D - CFD calculations of the flow are carried out . Two different turbulence models were employed and the results compared. The differences between experiments and calculations are explained by introducing a topological apparatus

This paper deals first with experimental measurement performed in a test chamber to investigate the characteristics of temperature and moisture distributions. The effect of moisture accumulation in building material is studied too. Then a new approach is introduced to describe the simultaneous heat and moisture transfer. The results has been compared with a CFD model.

In this study, an office with mixing ventilation is considered. The CFD analyses show that for high cooling loads it is useful to couple a cold ceiling to primary air system

Using the model developed in part 1 of this paper, the influence of material kinds, ventilation and air-cleaning device on VOC concentration in room is studied. The conclusion is that ventilation rate plays a very important role on VOCs concentration, but it affects little on VOCs emission rate.
