CFD simulation results show that the entrance velocity is about 24% higher than the local flow velocity, resulting into large surface shear force, is consistent with the experimental results.
CFD模拟结果表明，直管试样入口处局部流速比平均流速高约24%，表面剪切力大，与实验结果一致。

On the curve of the entrance ramp, keep your speed slow enough so that objects and people inside your vehicle are not pushed from the force created by turning the curve.
