有限要素シミュレーションに基づく傾斜棒状Ni/Mg₂Si複合材料の熱電特性に及ぼす構造条件の影響に関する定量解析

抄録

The rod-Ni/Mg₂Si composites with anisotropy in the thermoelectric properties were focused on, and the influence of the structural conditions (volume fraction and tilt angle of Ni rod) in the composites on the thermoelectric properties was investigated using a finite element simulation. The mixture laws in the thermoelectric properties were verified from the simulation results. The relations between the thermoelectric properties of the tilted rod-Ni/Mg₂Si composites and the structural conditions were quantitatively clarified. Furthermore, the thermoelectric performance of the tilted composites was calculated using the clarified quantitative relations, and the optimum structural conditions bringing the maximum thermoelectric performance were predicted.
