Abstract

A new method for improvement the performance of personalized ventilation (PV) by control of the free convection flow based of confluent plane jets was studied. The confluent upward plane jets were generated close to the front of human body by openings at the front edge of a desk. The inner jet supplied controlled air while the assisting outer jet supplied room air. The mixing between the two jets was minimized by control of the shear stress between the two flows. Thus the air of the inner jet was transported upward to the face. In this paper, manikin-based equivalent temperatures were analyzed under the condition with this PV method and there was no thermal influence by the flow except for the back of neck.
