Thermal Comfort Study Based on Airflow within a Passenger Compartment

Abstract:

It is important to analyze the temperature, airflow field, PMV-PPD index distribution within the passenger compartment to ameliorate the amenity and decrease consumption. A numerical model to assess the thermal comfort taking into account the different air velocity. This paper uses commercial software FLUENT to simulate 3-D temperature, PMV-PPD index distributions and flow field in a compartment passenger. The predicted results basically meet the requirement of thermal comfort except the local temperature around the lower region and the local air velocities around passengers’ head region. When the air-outlet temperature is 20 °C, air-outlet velocity 4 m/s is agreed to the thermal comfort. PMV index are about -0.4-0.6, and PPD index is less than 10%, which is agreed with passenger’s thermal comfort. The predicted values illustrate the uniformity of indoor environment in the occupied zone.
