Numerical Investigation on Performance Based Methodology for Developing the Vane design of AC Duct 2024-28-0004

To ensure proper airflow distribution inside the cabin, the AC duct vanes' ability to direct airflow must be evaluated. Objective of this work is to propose a methodology for developing the vane design of AC system duct. CFD based factorial analysis was conducted using three components at three levels. The impact of number of horizontal vanes, number of vertical vanes and distance between them on the pressure drop and face level velocity are investigated. It was observed that when the number of vertical vanes are increased, the vane's ability to direct airflow rises. In this situation, the pressure drop increases as well. When the number of horizontal vanes exceeds a specific threshold, the vane's capacity to steer airflow declines. In literature, it can be noted that a greater number of research are available that focus on the relationship between human thermal comfort and vent position. However, studies focused on vent assembly components such as vane design and the influence of number of horizontal and vertical vane are sparse. The present work is a comprehensive investigation that estimates the airflow directing ability of vanes. The proposed methodology provides a better understanding and more rapid design approach to determine how effectively AC duct vanes can direct airflow toward the manikin face.
