Transportation is closely related to our daily life. Until now, most passenger cars and ships are powered by internal combustion engines. Because of the oil crisis and environment concerns, it is very important to improve fuel injection systems, optimise existing engines for higher fuel efficiency and lower emission levels, searching suitable alternative fuels, and developing innovative power generation systems. On the other hand, over the past decade, the rapid development of computer has made numerical modeling a powerful design tool. However, it only helps at certain extend. Fundamental understanding of spray, jet and combustion is crucial in providing engineers with more reliable and accurate predicting results. While carrying out research in these fields, I see myself both as a pure scientist contributing to fluid mechanics, thermal engineering and development of next generation power systems and as an applied scientist following through to the application of these technologies. I believe that applications are a useful driver for innovation in technologies.
