Study of mechanism of influence of internal air flows on overall vehicle aerodynamics

Abstract

The article considers the problem associated with the influence of internal air flow on the aerodynamic drag coefficient of an automobile. The main part of the air flowing through the interior space of the car is used for blowing a cooling radiator, and at the same time aerodynamic resistance of the vehicle increases. The mechanism of this effect was investigated. It was found that the main factor is the interference of airflow flowing around the front part of the vehicle. It is caused by a decrease in the amount of air as the portion of air passes through the inside. Thus, the proportion of the aerodynamic drag associated with the airflow through the engine compartment depends on its flow rate.
