초록

이전 연구에서 우리는 나노구조와 화학연료의 동축 구조를 제작하여 이를 점화시켰을 때, 축방향으로 매우 빠르게 화학 반응이 전파되며, 이와 동시에 높은 비출력을 가지는 화학-전기 에너지를 생성할 수 있음을 증명하였으며, 이러한 현상을 열동력 파도로 명명하였다. 본 연구에서는 열동력 파도와 관련된 여러가지 물리적인 현상을 심도있게 다루려 한다. 나노구조의 다른 배열 상태에 따라 반응 전파속도, 에너지 생성 정도가 어떻게 달라지는지, 그리고 이와 동시에 발생하는 전기 신호와는 어떤 연관 관계가 있는 지를 연구하였다. 또한 이론적으로 온도 변화에 따라 달라지는 나노튜브와 화학연료의 성질, 대류와 복사에 의한 영향을 고려했을 때 열동력 파도의 전파 양상이 어떻게 달라지는 지를 규명하였다.

There is considerable interest in developing energy sources capable of larger power densities. In our previous works, we proved that by coupling an exothermic chemical reaction with 1D nanostructures, a self-propagating reactive wave can be driven along its length with a concomitant electrical pulse of high specific power, which we identified as a thermopower wave. Herein, we discuss details about many different aspects of a thermopower wave. Different alignment degree in vertically aligned CNT films is evaluated in the reactive wave speed and correlated with its thermal reaction that affects the change in the magnitude of energy generation. The effects of the temperature-dependent properties of chemical fuels and CNTs are evaluated. Furthermore, we explore the convection and radiation portions in this thermal wave as well as the synchronization between the thermal reaction transfer and the oscillation of the electrical signal.
