Professor Chengchun Zhang was awarded his PhD degree in engineering at Jilin University in 2007. Then he worked at Tsinghua University and Zhengzhou Yutong Bus Co., Ltd. as a research fellow for two years. After that, he joined Jilin University as an associate professor in 2009, and promoted to a professor in 2015. During that time, he worked at Imperial College London as a visiting professor one year. He has headed more than 20 scientific research projects including 1 National key R & D project, 3 National Natural Science Foundation of China, 1 Special research fund on civil aircraft, 1 Theme project of national defense science and Technology Innovation Zone of science and Technology Commission of CMC, and so on, published more than 50 articles in ACS appl. Material. Inter, Ocean Engineering, J. Colloid Interf. Sci, Int. J. Therm. Sci, J. Sound Vib., Soft Matter, J. Bionic Eng., and other journals, and obtained 20 national invention patents, 1 international patent.
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.
