Working on several projects including “CFD & FEM Analysis of gas quenching process of transmission ring gears” and “microstructure modeling of precipitation in aluminum alloys” for optimizing the production processes.

I am working on the project, “Nucleation by design” to develop a computational approach to engineering heterogeneous crystal nuclei in aluminium castings, and I also help with supervising students to do molecular dynamic simulations using DL_POLY and LAMMPS, and some calculations on the thermodynamic properties for new alloys using quantum chemistry codes (e.g. VASP) based on density functional theory. On the computation side, I also help with maitaining the computing cluster and helping with Linux script writting in the Materials Processing Group at Imperial College London. On the experimental side, I did synchrotron x-ray radiography at Diamond Light Source which has created huge amount of data for the future PhD students to work on.

I developed a Fe-rich intermetallic model within uMatIC and installed it for Ford Research and Advanced Engineering Lab. I also give the training on how to use the model to the Materials Scientists. This model is currently available through public GNU license on http://www3.imperial.ac.uk/advancedalloys/software . The model can predict the effect of alloying additions on defects(pore & Fe-rich intermetallics) formation. The defect distribution can also be predicted as a function of processing conditions which has been successfully used in the development of Ford V.8 engine block.

I helped solving problems in microstructure model by upgrading the version of uMatIC. I also give a training course on how to use the porosity model.

Coordinating the whole project “L2 Control System For Heat Treatment Process To Produce High Quality Steels” and taking charge of the project “Modelling of combustion, convection and heat transfer in a roller hearth furnace during the heat treatment of steels”. The key works include:(1) Developed a large software package using C and Visual Basic to simulate slabs’ moving and heating process.(2) Built a 3D FEA model solving for the transient temperature field and thermal-stress field with ANSYS8.0.(3) Predicted temperature distribution, fluid flow and NOx combustion waste inside the furnace using CFX.(4) Installed my mathematical model at Wuyang Steel Co. Ltd(http://www.wuyangsteel.com/) using the SIMENS Step 7 PLC and WinCC and developed a database with Microsoft SQL2000 for seaching pre-optimized production conditions.

I was in charge of the project “Swirled Flow Heat Exchanger”. With a deep understanding of the main theories in heatexchanger technology in my mind, I discovered the key factor to enhance the efficiency of heat transfer in a heatexchanger and proposed the practical methods to produce the fifth generation of heat exchanger. This kind of high efficiency heat-exchanger has been produced and used in the largest annular furnace in the world. In this period of time, I became not only proficient in mechanical drawing software such as AutoCAD2004, SolidWorks2003, and Pro/Engineering, but was also promoted to be a coordinator in a new development team.

I was acting as the secretary or assistant for the CEO in the Departmental spin-out company, Thermonergy High Tech. Co. Ltd. It sells the technology of “High-temperature Air Combustion”. It is a new form of regenerative burner using hexagon structure of honeycombs to recycle the energy from exhaust gas, reducing the NOx emission and energy consumption. As the CEO's assistant, I helped with a lot of projects biding and contract writting. Industrial application of our high-cycle regenerative burner system (HRS) and honeycombs burner have proven heat regeneration as much as 95% from the exhaust. Nowadays, with the development of the steel industrial in China, the technology of High-temperature air combustion has been spread all over the country and this company has been affiliated to the USTB instead of our Deparment. It has a annual turnover of ~200,000,000 RMB.
