초록
본 연구에서는 갤로핑/플러터와 웨이크 갤로핑과 같은 공력불안정현상을 이용한 에너지 수확 장치에 대한 적용가능성을 검토하였다. 이를 위해서, 작은 규모의 에너지 수확 장치를 설계 및 제작하였고, 이 장치들의 효율성과 효과를 증명하기 위한 일련의 실험을 수행하였다. 이러한 시험 결과로부터 공력불안전형상(갤로핑/플로터 및 웨이크 갤로핑)을 이용한 에너지 수확 시스템의 적용 가능성이 증명되었다.
Abstract
This paper investigates the feasibility of two newly developed energy harvesting devices based on aerodynamic instability (i.e., galloping/flutter and wake galloping). To this end, small-size energy harvesting devices are designed and manufactured. And then, a series of tests are carried out in order to validate the efficiency and effectiveness of the energy harvesting devices. From these tests, the applicability of the energy harvesting devices using aerodynamic instability (i.e., galloping/flutter and wake galloping) is experimentally verified.
