Modeling the performance of personalized ventilation under different conditions of room air and personalized air

In this paper, the numerical methods are first validated by experiments, then a seated computational thermal manikin (CTM) is used to carry out the parameters study of Personalized Ventilation .The modeling outcome shows that in a stagnant environment, the human body is enclosed by the thermal plume and its intensity is affected by the room air temperature.To tear away the thermal plume at the windward side of the human body, a uniform airflow in the horizontal level with a O,2 m/s speed is strong enough.
