Research on Flow Behavior, Ventilation Efficiencies and Inhaled Air Quality in a Truck Cabin with Cooling Mode

-Analysis of Impact on Ventilation Efficiencies and Inhaled Air Quality from Human Body Model-

Abstract

The comfortable environment in a truck cabin is important for a truck driver. Thus the purpose of this study is to discuss ventilation efficiencies and inhaled air quality in a truck cabin with human body model, which has not been considered in the previous research. In this research, at first, the flow behavior of a 1/3 scaled truck model is evaluated and the accuracy of CFD results is discussed by the comparison with experimental results. Then, the Ventilation Efficiencies and inhaled air quality are evaluated by CFD and the impact from human body upward flow is discussed.
