Comparison and Analysis on the Impact of Two Typical Rearview Mirrors on Aerodynamic Performance

Abstract:

This paper aims to study the impact of the rearview mirror shape on aerodynamic performance. Two typical rearview mirrors were selected to conduct the wind tunnel test, and the test result showed that the noise on the rear monitoring point of the mirror 1 was lower than that of the mirror 2. This paper then conducted simulating computation through computational fluid mechanics (CFD) theory and Fluent software, and obtained the size of the monitoring points of the two typical rearview mirrors, static pressure chart, motion pattern and turbulent kinetic energy distribution diagram, and sequentially analyzed the reason for more noise of the mirror 2. The study shows that different mirror cover structures have a great influence on the flow line flowing through the rearview mirror cover, and significantly influenced the rear flow field of the rearview mirror and the static pressure and the turbulent kinetic energy of the monitoring point.
