Abstract:

This research presents an investigation of high wind flow around a simplified trailer section of a high-sided vehicle using CFD simulations. Researchers investigated the problem of overturning high-sided vehicles through a fundamental fluid mechanics perspective. The research conducted included a background on overturning high-sided vehicles, the aerodynamic coefficients of interest including the rolling moment coefficient, the considerations for this study given the United States geographical focus, the background on Reynolds number (a measure of the ratio between inertial and viscous forces that helps predict fluid flow patterns) dependency as it relates to an overturning high-sided vehicle, and fundamental fluid mechanics of flow around rectangular cylinders. CFD high resolution simulations were assembled for this study to investigate the wind flow field and related aerodynamic coefficients around a simplified geometry of a high-profile vehicle.
