- Abstract
In order to reduce fuel consumption and vehicle exhaust emissions, it is necessary to develop new designs, such as flow control using jet actuators, to reduce vehicle aerodynamic drag. A numerical model was developed based on the process of airflow passed through a micro-jet actuator. Under different inlet pressure, the flow field and its characteristics were analyzed with computational fluid dynamics (CFD) method. The numerical results show that a high outlet airflow velocity can be obtained as the inlet pressure exceeds 1.0e5 Pa for this actuator. Therefore, this type of actuator can be used for vehicle airflow control to reduce aerodynamic drag.
