Abstract

Bionic flow control is to control the boundary layer state, flow separation and wake structure by imitating the structure/surface morphology of living creatures in the fluid medium to achieve the purpose of reducing drag, improving lift, and suppressing noise. It is widely used in the fields of energy, aviation and aerospace. The report starts with the principle of biological function, introduces the connotation of bionic flow control, and the bionic method of boundary layer and mainstream flow field control. It focuses on the hot issues of bionic aircraft and bionic power system design such as drag and noise reduction, water entry buffer and so on, and And give some practical application cases.  With the further development of bionics and advanced manufacturing technology, bionic flow control will certainly play a more important role in related fields. Figure 1 shows the related research on the bionic noise reduction of the power system; Figure 2 illustrates design of the trans-medium aircraft from the perspective of flow control.
