题目：Combustion of Bio-Oil
Professor Yang is currently a professor of the Department of Power Mechanical
Engineering at the Formosa University, and is also the Dean of Office of International Affairs of the Formosa University and serves as the Secretary General of the Combustion Institute of Taiwan. He received his Ph.D. in Mechanical Engineering from Central University in Taiwan in 2002 and was subsequently employed as a postdoctoral fellow at Princeton University (2003), working in the laboratory of Prof. C. K. Law. After returning to Taiwan, he joined the Industrial Technology Research Institute as a researcher. He began working at National Formosa University from 2009 until now. His research interests focus on combustion and biomass energy, including high pressure turbulent combustion, biomass pyrolysis and gasification technology, and spray combustion and droplet combustion of bio-oil etc.
Biomass is the fourth largest energy source in the world. The combustion technology from ancient times began with biomass. Biomass provides many energies through combustion, which is a very important source of energy for human beings. Today's issues of biomass are more important because of global warming and energy issues. This study is aimed at pyrolysis oil production of cellulose biomass, the characteristics of different components of biomass through different pyrolysis processes, and exploring the conditions of pyrolysis and biomass components for bio-oil components and production. The results show that volatile substances in biomass oil will cause ignition delay changes. The length of the burning flame is shortened, while the flame oscillates and the overall combustion heat value decrease. The part of the macro-compounds of the bio-oil causes the atomization flow field of the spray combustion to change, as well as the particle generation and the nozzle coking phenomena. The study of droplet combustion shows that after the fossil fuel is mixed with the bio-oil, the combustion characteristics of the droplets are changed. These characteristics include micro-explosion, change in the burning rate of the droplets and soot tail, etc. These characteristics are also demonstrated by the change in atomization length and flow field characteristics of spray combustion. This research could provide an interesting research direction of bio-oil application and basic combustion dynamics.
热冲压 (Hot-Stamping) 为冲压界新颖的成形技术之一，主要是利用金属板材在高温下具有高塑性、高延展性的性质，在透过模具进行模内淬火及成形，使板材获得超高强度的特性，其抗拉强度可达1400MPa以上，吾人之研究着重于提升热冲压技术，并拓展热冲压技术的应用，包含热冲压模拟分析、模具冷却水道之分析研究、差异温差模、无钉铆接连接技术、模内加热技术及热冲压制程测试设备开发等。
