The invention relates to a method for active flow control, a flow body and an aircraft. The method for active flow control includes generating a first local velocity field in a fluid flow by introducing a first vortex structure into the fluid flow by means of a first flow control actuator coupled to a first actuation site of a flow surface; and introducing the second swirl structure into the firstlocal velocity field by means of a second flow control actuator coupled to a second actuation site of the flow surface, the second actuation site being located downstream of the first actuation site,when the head swirl of the first swirl structure has been transmitted downstream of the second actuation site along with the fluid flow.
本发明涉及一种用于主动流动控制的方法、流动主体和飞行器。用于主动流动控制的方法包括:通过借助于联接至流动表面的第一致动部位的第一流动控制致动器将第一涡流结构引入到流体流中而在流体流中产生第一局部速度场;以及当第一涡流结构的头部涡流已经随着流体流传送到第二致动部位的下游时,借助于联接至流动表面的第二致动部位的第二流动控制致动器将第二涡流结构引入到第一局部速度场中,第二致动部位位于第一致动部位的下游。
