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.
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.
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.
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
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.
This paper presents a numerical method aiming at recreating the concentration field of a pollutant at each point of a ventilated enclosure that contains one or several pollutant sources of unknown emission rate.
Flow, temperature field and contaminant concentration distributions are analyzed using CFD for 5 different ventilation systems.
This paper deals with a 3D numerical study to assess the effectiveness of a displacement ventilation system to remove particulate pollutants, generated in the occupied zone of a room.
