..., for instance, the postcollisional populations are the equilibrium populations f i ′ = f i e q . After the collision step, the postcollisional populations are then propagated to the neighbor sites. Lattice Boltzmann method Drag coefficient Lift coefficient Simulations...

..., which can accurately predict the vehicle motion characteristics in the road driving process. The new approach simulates the vehicle aerodynamics on the road by taking into account the pitch angle changes during vehicle motion. Findings By comparing the transient drag coefficient on road...

...Zhanhong Wan; Luping Li; Zhigen Wu; Jiawang Chen; Xiuyang Lü Purpose The behaviors of sea surface drag coefficient should be well understood for an accurate hurricane prediction. The speed of wind has been applied to characterize the spray production; however, this could result in inaccurate spray...
