Delivering a better understanding of unsteady wakes has real potential to further our future capabilities of reducing bluff body parasitic drag. The national benefit derived from this project is the advancement of knowledge of a complex fluid mechanics problem, with secondary benefits arising from the specific and practical application to sports aerodynamics. By better understanding the wake structure and its interaction with a locally oscillating bluff body this knowledge can feed into the field of active flow control in the transport sector. The potential for emissions mitigation by lowering aerodynamic losses in the ground transportation section through active aerodynamic control is significant.

更好地了解非定常尾流对我们未来降低海崖体寄生阻力的能力具有真实的潜力。该项目的国家效益是提高了对复杂流体力学问题的认识，其次是对运动空气动力学的具体和实际应用。通过更好地了解尾流结构及其与局部振荡海崖体的相互作用，这些知识可以用于运输部门的主动流动控制领域。通过主动空气动力学控制降低地面运输部分的空气动力学损失来减少排放的潜力是巨大的。
