Thermoelectrics
Thermoelectric applications have emerged as promising alternative applications for environmentally friendly heat pumps and power generators since the environmental issues such as the global warming and the limitations of energy resources gradually drew global attentions. Due to their distinct advantages, the thermoelectric application has become a potential green technology which has been used in different areas in the efforts of contributing to achieve simplified and compact system structures and environmental friendliness.
Now I am dedicated in the research and development of domestic thermoelectric cogeneration system. It uses the boiler waste heat and solar radiation as the heat sources and produce electrical power and pre-heated water for domestic boiler. Hence, it recovers the heat to the maximum level which shows much higher heat recovery efficiency than the conventional applications which recover heat by generating electrical power only.
Drag reduction (Inspired by the shark and dolphin)
Since energy consumptions increase year after year, energy scarcity has become a critical problem that we have to face in the 21st Century. New and innovative technology is needed to meet energy conservation requirements. High efficiency of energy utilization contributes not only to energy saving, but also to improving the environment. Viscous drag has been considered one of the major barriers to further optimization of most aerodynamic and hydrodynamic devices. In the long term, significant drag reduction can contribute immensely to the achievement of energy saving. Even a small amount of drag increase can have a great economic impact if a large number of units are involved.
Turbulent flow has been the kernel flow regime that the drag reduction researches have focused upon. In the pursuit of a drag reduction technique with high efficiency and great performance, insights have been taken from the nature in an effort to look for answers of controlling drag reduction in a more effective way. Since the nature has a clear priority for the development of drag-reducing surfaces, the evolved abilities and characteristics of creatures are the sources of inspiration which enable researchers and engineers to find a better way of creating remarkable designs and solving technical problems.
For the low-drag-oriented characteristics in the nature, studies have been carried out to investigate the special structures shown in the skin of marine animals such as the shark, dolphin, seal and penguin as their “talents” are believed to be due to their skin architectures. Riblet surface, inspired by the skins of fast sharks, has been seen as an effective turbulent drag reduction method which reduces flow drag by changing the position of the origin of velocity profile. However, the riblet surfaces adopted so far only give a limited range of drag reduction due to the rigid structures which bear the flow passively. A “smart surface”, consisting of trapezoidal riblet and elastic coating, is designed to widen the range by enabling the wall surface to be self-adjustable, and interact with the boundary layer under different flow conditions and adjust the wall structure accordingly. An overview of the common methods of turbulent flow drag reduction and shark-inspired surface-riblet for drag reduction is presented and the “smart surface” is suggested and discussed in an attempt to approach the advanced biomimicry in this paper (A biomimetic smart control of viscous drag reduction)

Venturi pump
KTP is the Knowledge Transfer Programme run by the University of Nottingham. It is cooperated by the university side and the industry side. Working with CE technology Ltd, the purpose aimed at investigating and developing a venturi pump. Modified designs have been carried out according to the simulation results.
Job experience in the UK
Lez Wright
I have received personal development from Mr Lez Wright who has been dedicated in changing people's lives from three aspects: Food, Thought and Fitness. It was a 12-weeks one-to-one personal training. My capability on fighting against the stress has been tremendously enhanced, my working efficiency has been dramatically improved and my energy level has been elevated significantly. I can control myself more easily than before due to my strengthened willing power on what I do without procrastinations. My prospect on life has been changed by experiencing the close relations of Food, Thought and Fitness which I had never thought have any connections with each other. I have experienced all the changes in myself.
Meanwhile, I was maintaining and developing the website. I started from a scratch and has delivered incredible achievements in a short period. My perception on difficulties in my life became very positive which enabled me to see the problems in a different way. I must say, this experience is a cornerstone and a life-long benefit in my life.
BEcause
Working for BEcause as a brand ambassador for TIGER beer and Bulmers in Hyperama and Sainsbury's Castle Boulevard store.
I went for a one day professional training in Comedy Store, Manchester. I have received the training for promoting the release of Bulmers new product : Bulmers No.17. The training includes the introduction of the brand history and the communication with customers.

Research experience in China
①.An electric heater test(8/2007)
Brief introduction:
The heater is designed to be used on the trains which run among areas with low pressure. The heater’s performance is different under low pressure from normal pressure. The test purpose is to study its performance under low pressure and find out overheat protective temperature through which the heater’s switch is controlled by the program.
②.An optimization to an air filter with Solidworks and CFD(9/2007~10/2007)
Brief introduction: (refer to: Fig.1 and Fig.2)
The air filter was supposed to be used at the fresh air inlet on the train air condition system to remove the dust from fresh air so as to ensure the indoor air quality of the train. The simulation was to optimize the filter’s size and the vane’s structure.
