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.
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.
Experiment and CFD simulation show the influence of moving person simulator (of cylinder shape) and thermal manikins on air distribution in ventilated rooms.
That study aimed at investigating the contaminate distribution in and around a naturally ventilated livestockbuilding with and without an upstream obstacle.
This paper is a presentation of a theoretical and experimental analysis of supply air jet flow patterns in a mixing ventilation system. Investigation procedure aims at reducing draft risks.
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
The paper deals with the CFD analysis performed for a family house residence, which is in the design phase : the aim was to test several concepts for heating ( floor heating, floor convectors, both systems) in terms of thermal comfort.
This paper deals with an approach to a multizone airflow analysis that can account for mechanical energy conservation. It is shown that the resistance (dissipation) provided by zones in a multizone analysis should not be ignored.
