Profile

Sun Longquan, born in Harbin, Heilongjiang in 1983, is currently Vice President of the College of Science and Technology at Harbin Engineering University, a Doctor of Engineering, Professor of Ship and Ocean Engineering, and a Ph.D. advisor.
He has conducted fundamental mechanical research on the dynamics of underwater bubbles and their coupling with structure, mainly focusing on the load characteristics of bubbles in water, the fluid-solid coupling analysis of bubbles and the water-exit/entry vehicle motion, the free surface-bubble interaction analysis, and experimental research on vehicle with bubbles during water-exit. As the project leader, a National Natural Science Foundation Youth Fund project, a Joint Fund key project (as the unit leader), a Technical Field Fund project, and more than 10 other projects such as preliminary research have been conduct. And participated in 2 National Natural Science Foundation Key Projects, 3 General Projects and 2 Basic Research Projects. More than 30 papers have been published in academic journals such as Chinese Journal of Theoretical and Applied Mechanics, Physics of Fluid, Ocean Engineering, and Applied of Ocean Research for research on the dynamics of cross-medium during the water-entry/exit of vehicle. The scientific research achievements have won 2 second prizes of Provincial and Ministerial Awards for Scientific and Technological Progress, one third prize of Provincial and Ministerial Awards for Scientific and Technological Progress, one second prize of Provincial and Ministerial Awards for Scientific and Technological Progress, and one second prize of Marine Engineering Awards for Scientific and Technological Progress. Authored more than 10 invention patents, 2 conversion patents, more than 10 software copyrights, published a graduate textbook, and served as a long-term reviewer for journals such as Ocean Engineering, Acta Armamentarii, and Journal of National University of Defense Technology.
