| Research Abstract |
High temperature thermal energy surface coatings have been developed to achieve advanced thermal managing system. The key concept of the coating is to apply interference effect of electromagnetic wave using oxide ceramic multi layer structure. Application of the interference effect to thermal energy control needs (1) wide wavelength interference design and (2) high reflection over wide incident angle of electromagnetic wave. To solve these problems, three-dimensional wavy surface morphology is employed for design of the coatings. To design three-dimensional wavy surface, simulation is used : the procedure is evaluated to compare model results with experimental ones. Simulation results demonstrate the effectiveness of the wavy surface layer on thermal energy reflection. The maximum possible reflectance estimated from this simulation is larger than the flat surface. It is concluded that the present thermal energy control surface is effective way to control thermal reflection energy at high temperatures.
