“…The panel-vent mode is such that each of the four inlet vents in the dashboard panel, indicated with numbers 3 and 4 in Figure 2, are open, while all the other vents are closed. The fans grille has been positioned with a neutral tilt and fixed with clips, according to previous studies by Adhikari et al [10] and Piovano et al [11], showing that an accurate fixing position of the grille is decisive for a repeatable examination of the air distribution in a car cabin. No modifications have been made to the interior parts of the car cabin, including the seats, side doors, ceiling, and floor.…”

The ventilation flow in a car cabin has been experimentally investigated. The study has been carried out in a car commercially available, by testing one ventilation mode (panel-vent mode) at one fan strength (level 3 of the 4 available) with fresh air intake (without any re-circulation). The flow velocity at the exit of the vents has been measured using a 5-hole pressure probe. The flow velocity fields inside the car cabin have been measured by particle image velocimetry (PIV) in three longitudinal sections: (i) the car centre plane, including both the front and rear area; (ii) the driver’s seat centre plane, only in the front area; (iii) the passenger’s seat centre plane, only in the front area. At these longitudinal planes, the time-average flow velocity is presented and discussed. The experimental results provide new insights in the ventilation flow in a car cabin.

“…VTC is challenging because of the varying influence of solar load on indoor airflow and temperature distribution [3]. The cooling vent setting and velocity of inlet air also influence the air distribution, which eventually affects the temperature distribution in the cabin [4]. In this regard, the automotive industry has continually been facing confrontation for a comfortable and efficient thermal environment for all the occupants.…”

The paper presents the human thermal comfort inside a car cabin using three-dimensional numerical analysis and state of the art comfort models. Vehicular thermal comfort is a must concern factor in modern car manufacturing industries. Numerical simulations have been performed to accurately predict the temperature inside the car cabin and velocity of airflow. The numerical results are then compared using Fanger’s model, the equivalent temperature model and the modified Fanger’s model. A link has been developed using a general thermal comfort index for the considered human thermal comfort models. The general thermal comfort index takes into consideration all the investigated parameters that affect the vehicular thermal comfort thereby evaluating the whole car environment. The thermally comfortable conditions for the driver and passengers in a vehicular cabin are also addressed based on some of the thermal comfort indexes available in literature. In addition, the solar load has also been added using a surface radiation model to consider the environmental heat load effect on cabin thermal comfort.
