CFD study on personal exposure with personalized ventilation system

For the investigation of the personalized ventilation efficiency and the study of human exposure in a displacement and mixing ventilated room, a seated computational thermal manikin with the geometry of a real human body has been used. A RNG k-e model with low Reynolds number has been used for the simulation.
The thermal plume around the human body plays a key role for the determination of the inhaled air quality.
According to the authors, the application of personalized ventilation is able to improve the inhaled air quality greatly.
