Since he joined the faculty of Institute of Applied Mechanics of National Taiwan University in 1989, Professor Falin Chen has devoted himself in three major research fields. First of them is the stability of fluid flow, which applies on various engineering disciplines, such as alloy casting, film coating, underground water motion, jet, gravity current, and so on. The second is regarding the engineering applications by analyzing the ventilation in road tunnel and subway system to comply with the booming infrastructure development in Taiwan. Recently, due to the global warming issue and the severe energy situation of Taiwan, he has devoted most of his research effort to the energy-related researches, such as the Kuroshio power harness, the water and thermal management of the hydrogen fuel cells, the strategy of CO2 emission abatement. In the past two decades, he has been author or co-author of more than 100 papers, all are refereed and published in internationally renowned journals such as J. Fluid Mech., Physics of Fluids, Physical Rev. E, Appl. Mech. Rev. (ASME), J. Heat Trans. (ASME), Int. J. Heat Mass Trans., J. Appl. Physics, and J. Power Sources.
