진동하는 두 평판 사이의 거리 및 위상차의 영향

다국어 초록 (Multilingual Abstract)

The unsteady flow fields generated by two plates were computed using a commercial flow solver. Based on the validation for a single vibrating plate, the effect of the distance and phase angle difference between two plates were analyzed by using the unsteady flow and the time-averaged velocity distribution. When two plates were vibrating in phase, their performance was inferior to the single plate regardless of the distance in terms of the maximum velocity and mass flow rate. Otherwise, two vibrating plates in counter-phase generated stronger axial flow and two times more flow rate for cooling than the single plate, unless the plates were too close. It was found that the optimal distance between two plates in counter-phase might be twice the size of the fully-grown vortex generated by the single plate. In addition, an attempt has been made to explain the performance variation of two vibrating plates based on the vortex-interaction.
