Research Status
Prof. Suyuan Yu has engaged his research activities in a diversity of research domains such as Particuology (aerosol), active magnetic bearings, structural mechanics, the advanced nuclear reactor technologies.
Since 2013, Professor Suyuan Yu has undertaken several national key R & D projects, mainly engaged in the research on aerosol migration and evolution law under severe nuclear reactor accidents, the mechanism of impact of emissions from key industries on the burst growth of atmospheric particles, and the coupling mechanism between magnetic bearing and supporting components. Especially in the field of magnetic bearing, Professor Yu proposed a non-differential control method of magnetic bearing, developed the anti-shock technology of magnetic bearing, the redundant fault tolerance technology of control system, and the composite support technology of electromagnetic bearing. The active control magnetic bearing was applied to vibration and noise reduction of rotating machinery.
From 1999 to 2013, he had initiated the primary research and design of the helium gas turbine in HTR-10 and the study of HTR-PM demonstration plant, both of which are key projects in the State 863 Program. A series of research had been carried out in the study of the helium turbine-compressor system, the compact heat exchanger, the flexible rotor magnetic bearing, the reliability study of the graphite structure of HTR-10, the oxidation and creep behavior of nuclear graphite, the study of the growth, development and sediment of graphite particle in HTR-10. He also took part in the research and design of the core structure of 20MW high flux test reactor core, the feasibility study 200MW heating reactor, the design of China 200MW small boiling water reactor (collaborated with Toshiba, Japan), the research on the structural features of multi-purpose small power reactor (collaborated with Hitachi, Japan), the safety analysis of the Fast Breeder Reactor key components and the research in the response spectrum and stress calculation of China Advanced Research Reactor (CARR).
Besides, Professor Yu also conducted the kinetic study of chromium waste incineration (funded by National Natural Science Fund). Moreover, Prof. Yu principally investigated the Sino-Australia Special Scientific Cooperation Project “Quantum Study on Chromium Incineration” during 2006-2009 (No. 50711120414).
Dr. Yu’s post-doc program in Yale University from 1998 to 1999 focused on the kinetic research on high temperature chemical reaction and the research on the mechanism of nano-particle development which paved the way for the development of new chemical and electro-industrial material. The production of Al2O3 in counter flame was completed in the lab during the post-doc research from 1998 to 1999.
The research on the hazardous waste disposal was carried out under the supervision of Professor Ian M. Kennedy, an internationally renowned expert during his PH.D. research from 1994 to 1998. The two-dimensional DSM particle kinetic model and the chromium kinetic model in high temperature chemical reaction were established and the precise examination of the complex particles was maintained by means of laser scattering technology. The research has won favorable comments from US Environmental Protection Administration (EPA), US National Institute of Environment and Health Science (NIEHS/NIH) and the experts from the field of combustion. The researcher was accordingly awarded the Super Fund sponsored by National Institute of Environment and Health Science (NIEHS/NIH) from 1995 to 1996 and 1996 to 1997. A keynote speech based on the research was delivered at the tenth anniversary of the Super fund.
Between 1989 and 1994, Dr. Yu participated in the feasibility research on and design of the pressure vessel of the 10 MW High Temperature Gas-Cooled Reactor, the research and design of the pressure vessel of 200MW heating reactor which has won the award of National Scientific Breakthrough by the State Science Committee. The success of the R&D of hydraulic tensioner won the Awards for the Great Scientific Breakthrough in the State Eighth Five Year Planning Period. The hydraulic tensioner was granted the Utility model patent and passed the examination from the State Education Committee
