... box truck lift drag vortex wake flow separation Abstract The aerodynamic performance of medium-duty box trucks significantly impacts fuel economy and environmental sustainability. However, research on their aerodynamics has been limited compared to heavier trucks. This study uses...

... boxy car lift drag vortex wake flow separation Abstract This study investigates the aerodynamic qualities of a sub-compact car with a boxy shape using a two-dimensional (2D) model. The research examines the flow over the vehicle and the lift and drag forces that can affect fuel...

... to simulate average cruising speeds of each shark species at angles of attack of 0 , 12 , and -12 degrees for neutral, rising, and diving movement patterns, respectively. We compared the output drag and lift coefficients to coefficients generated using CFD simulations in STAR-CCM+. Across the three species...

..., vortex generation, aerodynamics, drag, lift 1. INTRODUCTION Increasing fuel economy and vehicle stability are common topics in the automobile field. Reducing drag force helps increase fuel economy while increasing down force can improve vehicle stability during high speed and turning. Vehicle exterior...

... and to minimize vibration. Rotor harmonic airloads are generated from the rapid variation of flow around the rotor blade due to the vortex wake. A rapid drop in the circulation near the blade tip causes tip vortices which are the reason for the maximum lift at the tip of the blade. Consequently, tip vortices...
