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.

This paper presents a universal but simple mathematic model very useful to predict Volatile Organic Concentration in the bulk air for different conditions in residential buildings.

CFD is a suitable tool to calculate concentration in particle contaminant distribution in a room. 3 approaches are described for two types of flow problems and compared in this paper.

The study used CFD to examine reactions between ozone and terpenes in a room under 4 conditions. The study indicates that chemical reactions can significantly alter the concentration of air pollutants, an imperfect mixing may result in reactant and product concentrations significantly different from those predicted by the model that assumes fully mixed conditions.
