Introduction of the Department

Mechanical Engineering

 Mechanical Engineering Course offers the education and the excellent environment of researches regarding the development of machines, the improvement of performance and the manufacturing processes. The Course includes material processing, material strength, utilization of thermal energy, fluid flow system, energy conversion, measurement of mechanical system, control, dynamics, vibration, machine design, manufacturing engineering and so on. The students will have a skill of the design and the development of flexible and multifunctional machine systems with a computer-aided technology.

1. Materials Engineering

 Research interests are to elucidate the failure mechanisms of engineeringmaterials and to develop the evaluation method for strength of structures. Low-cycle fatigue strength of structures, resistance features of materials under various environments (low & high temperature, jet flow, corrosive environment) and crack driving force solution for various structures are studying. Educational objective is to bring up excellent engineers and researchers who have a sense of selecting proper materials in the structure design based on synthetic consideration on manufacturing process and maintenance of structures.

2. Thermal and Fluid System Engineering

 On the basis of thermodynamics, fluid dynamics, transportation phenomenon and energy conversion, education and research of phenomenon on heat and fluid energy are carried out. In the thermal system field, the heat transfer phenomenon which is important for energy saving is clarified, and the effective utilization of thermal energy is studied. In the fluid flow system field, the non-Newtonian fluid flow and the flow phenomenon concerning the fire are studied. In the energy conversion field, the visualization image processing and analysis of the multi-phase flow are studied.
