任務/Mission

Radiation heat transfer is one heat transfer mode besides conduction and convection. Its characteristics include: (a) Intervening medium is unnecessary; (b) Heat transfer rate is related to the fourth power of absolute temperature; (c) Heat transfer rate depends on direction and relative orientation between absorber and emitter; (d) The rate may differ with wavelength of thermal radiation. Thermal radiation dominates in many fields, such as solar energy utilization, cooling in space, ore smelting, material rapid thermal annealing, combustion and flame, waste heat recycling, and cryogenic research. The length scale varies from a few nanometers (among electronic heating devices) to the size of our whole world (global warming).

On the other hand, research topics of optics and photonics are partially overlapped with those of thermal radiation because they aim at light or electromagnetic waves. Ultraviolet, visible, and infrared light are all within the scope. As a result, optical responses (absorptance, emittance, reflectance, and transmittance) are also reviewed as radiative properties.

Dr. Yu-Bin Chen is the principal investigator (PI) of Radiation Thermophysics and Engineering Laboratory (RTELab). He leads a team mainly composed of students from Department of Power Mechanical Engineering, National Tsing Hua University, Taiwan. The team explores all scopes related to thermal radiation. Simultaneously, members have a lot of fun in the great ocean of truth. Each team member has his/her own project, but members support each other. Tools at their hands include logic, physics, mathematics, optics, electromagnetism, and engineering training. They gain new knowledge and obtain fruitful results during everyday at RTELab.
