Assessment of flow and force predictions on representative high-sided vehicles at multiple yaw angles using SST-DDES

Abstract

This paper aims to evaluate the capabilities of the k-omega shear stress transport delayed detached-eddy simulation (SST-DDES) model for predicting the flow field around two benchmark high-sided vehicles ranging from a highly simplified generic body to a near-realistic truck across several discrete yaw angles. It also explores whether specific turbulence modeling modifications can enhance accuracy under large-yaw conditions.
