Performance analysis with SiC nanoparticle enhanced Bi-Te-Se-Sb alloy-based thermoelectric materials for variable leg geometry
Source abstract
Abstract
This research focuses on the thermoelectric (TE) material by incorporating SiC nanoparticles to investigate nanocomposite-based materials’ characteristics and the TE system’s overall performance. In this paper, a comprehensive analysis has been studied on the TE materials and SiC nanoparticles’ morphology to present the shape, size, and distribution by considering scanning electron microscope (SEM) and X-ray powder diffraction (XRD) technologies. The result indicates that adding SiC nanoparticles with TE materials considerably improved the system’s performance by decreasing the thermal conductivity (30.7%) and increasing the Seebeck coefficient (7.5%). Furthermore, a numerical investigation has been conducted on the performance analysis of the rectangular and trapezoidal-shaped TE legs. It is reported that the rectangular-shaped TE unit generates more power output around 3 µW and 2 µW compared to the constant and non-constant volume TE leg geometry, respectively, at a load current of 0.04 mA under a temperature difference of 100 °C. The rectangular-shaped TE unit outperforms the trapezoidal-shaped TE unit. However, the rectangular-shaped TE leg requires comparatively high TE materials (34.5%), increasing the investment by 33.9%.
