By means of CFD, the results of that study express a significant influence of Computer Simulated Person geometry on local flow pattern and on personal exposure to contaminants released from the floor surface.

Experiment and CFD simulation show the influence of moving person simulator (of cylinder shape) and thermal manikins on air distribution in ventilated rooms.

This study presents a model to predict the time required by a pollutant to disperse in a room, due to the effects of room occupancy (a moving person enhances the mixing of pollutants).

The experiment shows that the temperature and velocity fields generated above a seated person are comparatively better approached by a thermal manikin rather than a cylindrical dummy.

A model of an UFAD system in a ventilated room is proposed , the room is ventilated with one heat source and one cooling vent as a two-layer stratification.

That paper presents the results of a thermal comfort evaluation research in a brazilian office building : the measurements show that an underfloor air distribution system can provide comfortable conditions for both sitting and standing occupants along with a reduction of the energy consumption .

Few studies dealing with the effect of displacement ventilation on humidity gradient in a hot and humid region have been made . In this paper it is done with a case-study approach (measurements were made in a factory located in the Tropics). The results indicate that the humidity gradient is as significant as the temperature gradient..

That study aimed at investigating the contaminate distribution in and around a naturally ventilated livestockbuilding with and without an upstream obstacle.

A wall return and a ceiling return air arrangements of turbulent type clean rooms are presented in this paper. The influences of obstacles on the flow fields are compared by a numerical simulation.

Critical parameters such as the particle source location, air supply inlet design, operating table location, and lamp design are responsible for the particle distribution within the operating room, they have been investigated by means of CFD.
