Seminar - New Concepts of Regenerative Resources Development and Usage by Prof. Chang-Hsien Tai

Date:   08 November 2012 (Thursday)

Time:   2:30 pm – 3:30 pm

Venue:  EF305, The Hong Kong Polytechnic University


The development and application of wind power for renewable energy has attracted growing interest in recent years. Renewable energy sources are attracting much alteration as they can reduce both environmental damage and dependence on fossil fuels. With the growing need for sustainable energy supplies, a solution is made for decentralized, stand-alone power supplies (SAPS) as an alternative to power grids. In the era when the traditional petroleum energy resource is decreasing while the green house effects are significantly increasing, the development and usage of regenerative resources are inevitable.  Due to the contribution of the pioneers, the development of regenerative resources has already attained a remarkable achievement.  However, in the view of economy and quantity, it is still a long way from replacing the traditional petroleum energy with the regenerative energy.  In our perspective, instead of investigating larger regenerative energy equipment, it is much wiser to think about the blind side and breakthrough of the current technique. The technology closely associated to the renewable energy mainly covers various aspects including the collection of the energy, its transfer, its storage, its phase change and finally its applications.  Because of its very low efficiency and limitations in material properties, the storage technology is one of the areas that demands immediate breakthrough.  The design concept of such a hybrid system has lately been a popular research topic all around the world.  This paper has investigated a series of hybrid systems with new conceptual designs combined with the basic sciences of aircraft engineering, gas dynamics, aerodynamics, mechatronics, etc.  Some strategies were also introduced in this paper to deal with the transfer and storage problems in renewable energy.


Prof. Chang-Hsien Tai graduated from the Chung-Cheng Institute of Technology(CCIT), TAIWAN, with BSc in Mechanics Engineering(1979), MSc in Mechanics Engineering at Taiwan University(1983), MSc in Aerospace Engineering at University of Michigan (1987), USA, and PhD in Aerospace Engineering, University of Michigan(1990), USA. From 1993 to 1994, he worked as a Visiting Professor in IBM Watson Research Center,  USA, and a Researcher at NASA Langley ICASE, USA. From 1994 to 1999, he worked as director at the numerical Simulation Lab., CCIT, TAIWAN, then he became professor of Dept. of Mechanics Engineering in 1995 and Chairman of Dept. of Mechanics Engineering in 1997. He was  the chairman of Dept. of Vehicle Engineering, NPUST, TAIWAN in 1999 and Dean of Institute of Technology in 2002. Now he is the academic vice president of NPUST, TAIWAN. His current research interests are on the development of CFD algorithm and its applications, design of wind power system/ hybrid power system and shock interaction and its applications.
