周期力场下窄通道内汽泡滑移实验研究
Experimental study of bubble sliding in a narrow channel in a periodic force field
摘要
Abstract
The purpose of this paper is to explore the mechanism of the boiling heat transfer and to improve the two-phase flow model under ocean conditions. Bubble sliding in a narrow rectangular channel in a rolling motion was ex-perimentally studied by using the high speed camera in this paper. The results show that the bubble sliding velocity was periodically changed with the rolling motion and the period of the variation was similar with that of the rolling motion. The effects of additional inertial acceleration on the buoyancy force and the variation of the flow rate caused by the rolling motion will not influence the fluctuation of the bubble sliding velocity in the periodic force field. The variation of the bubble size caused by the rolling motion is the key factor that determines the fluctuation of the bub-ble sliding velocity.关键词
