Abstract

A finite element method is used for analyzing the resonance characteristics of circular wind tunnel. Two-dimensional circular wind tunnel with one and three slots is considered. The wind tunnel resonance characteristics are affected by the number and position of the slots of the wind tunnel. The resonant frequencies for the vertical vibration mode are higher than those for the horizontal vibration mode. The resonance frequencies increase as the open area ratio increases.

본 연구에서는 슬롯을 가지는 2차원 원형 풍동에 대하여 슬롯의 갯수, 크기와 흐름의 속동에 따른 공진 특성을 2차원 8-노드 등계수(isoparametric)요소를 사용하여 해석한다.
