Biography
Chung K. Law received a Ph.D. in Engineering Physics from the University of California at San Diego in 1973. He is the Robert H. Goddard Professor of Mechanical and Aerospace Engineering at Princeton University, the Founding and Honorary Director of the Center for Combustion Energy at Tsinghua University, and a past president of the Combustion Institute (2000-2004). His research interests cover various physical and chemical aspects of fundamental combustion phenomena, with applications to propulsion, energy, fuels and the environment, as reported in over 600 journal articles. For his research accomplishments he has been honored with various professional awards. He is a member of the US National Academy of Engineering (NAE), and a fellow of the American Academy of Arts and Sciences (AAAS), the American Institute of Aeronautics and Astronautics (AIAA), the American Society of Mechanical Engineers (ASME), the American Physical Society (APS), the American Association for the Advancement of Science (AAAS), and the Combustion Institute (CI).
Abstract
The advance and closure of a specific class of scientific investigation can be inhibited, knowingly or unknowingly, by the lack of understanding and possible resolution of certain key sub-processes. Removal of such roadblocks can invariably lead to robust advances. We cite herein two such examples, respectively on chemical kinetics and fluid mechanics, as: (1) Understanding and analytical description of the classical Z-shaped radical-induced explosion limit of H2-O2 mixtures, leading to potential drastic simplification in their prediction of complex situations. (2) Understanding of the non-monotonic response of colliding droplets and liquid-gas interfaces in terms of coalescence, bouncing and splattering, leading to their satisfactory description in natural and technical processes. The joy of achieving and applying such understanding is noted.
