Key Laboratory of Bionic Engineering (Ministry of Education, China), Jilin University
Professor Chengchun Zhang was awarded his Ph.D. degree in engineering at Jilin University in 2007. Then he worked as s research fellow at Tsinghua University and Zhengzhou Yutong Bus Co., Ltd. for two years. After that, he joined Jilin University as an associate professor in 2009 and was promoted to professor in 2015. During that time, he worked at Imperial College London as a visiting professor for one year. He has headed more than 20 scientific research projects including 1 National Key Research and Development Program, 5 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 23 national invention patents, and 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 and 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 gives 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.
