Numerical simulation of the aerodynamic characteristics of heavy-duty trucks through viaduct in crosswind
In our numerical simulation the hybrid mesh and the SST k-ω turbulence model are adopted
to investigate the variations of the aerodynamic loads and the flow field of heavy-duty trucks
while crossing a viaduct with 1.1 m high fences in a crosswind at a velocity of 20 m/s. The
results show that, with the protection of a fence, the side force is weakened, and the rolling
and yaw moments are strengthened while the truck is crossing the viaduct, which relatively
reduces the roll-over safety and the driving stability of the truck. Meanwhile, the direction of …
