Full-scale laboratory measurements combined with numerical simulations were undertaken to evaluate CFD capability to predict the pesticide dispersion in a naturally ventilated building. CFD successfully reproduced the trends but overestimates the mixing inside the building.
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.
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 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.
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.
