Abstract
A boundary condition treatment to enable the simulation of full-scale class 8 trucks with realistic treatment of the relative velocities between truck, wheel assembly and the road is presented. The rotating wheel boundary condition is validated using data from isolated wheel and wheel assembly experiments. Validations of the base flow solver in steady and unsteady modes are performed using wind-tunnel experiments with the Generic Conventional Model (GCM). Results from full-scale truck simulations with rotating wheels and a moving ground plane are summarized.
