Ventilation Efficiency of Personalized Ventilation: CFD Study

In this paper micro-environment around human body with a personalized ventilation system ina displacement ventilated room was simulated by the standard k-e model. The geometry of thecomputational thermal manikin (CTM) is a real representation of a human body. Detailed analyses of air flow at the facial region and inhaled air quality improvement with personalized ventilation system were carried out with the aid of this complicated CTM. The best inhaled air quality, which was denoted by pollutant exposure reduction index, was achieved at the personalized air flow rate of 0.8 l/s in our numerical simulation.
