Abstract

A coupled governing equation of thermoelectric materials can be converted into an uncoupled form to predict the effective Seebeck coefficient of thermoelectric composites, where modified Eshelby model is adopted. The predicted results by the present approach for serial- and parallel-connected composites and composite with spherical inclusions are compared with theoretical and experimental results from literatures to be justified. It is shown that the predictions by the theoretical approaches coincide exactly and show in good agreement with the experiments.

열전 복합재의 성능을 파악하기 위해 결합된 형태의 지배방정식은 결합되지 않은 형태로 변환되며, 여기에 수정된 에쉘비 모델을 적용하여 복합재의 등가지벡계수를 유도한다. 모재와 충전재가 직렬 및 병렬로 배치된 복합재와 모재 속에 구형의 충전재가 포함된 복합재에 대한 본 연구결과는 참고 문헌에 알려진 이론적 및 실험적 결과와 비교되며, 이론적 결과와는 완전히 일치하고 실험적 결과와 잘 일치함을 보인다. 지배방정식의 단순화를 통해 열전 복합재의 등가지벡계수는 수정된 에쉘비 모델로 성공적으로 예측될 수 있음을 보였다.
