进行了初步实验，以研究使用一种相对新型的射流致动器(拉曼和拉古[1])与附加的尾部车身相结合来减少标准半挂车上的阻力的可能好处。激励器产生振荡喷流，形成流向涡，显著增强了剪切层的卷吸作用。考虑到在拖车上添加任何附加组件的潜在可行性，我们选择了7个几何形状简单的不同车身进行调查。
Preliminary experiments were carried out to investigate possible benefits of using a relatively new type of fluidic actuators (Raman & Raghu [1]) in combination with attached aft bodies to reduce the drag on a standard semi-trailer truck. The actuators generate oscillating jets that cause the formation of streamwise vortices that enhance the entrainment of the shear layer significantly. Taking into account the potential feasibility of any add-ons to a trailer, seven different bodies with simple geometries were chosen for this investigation.
