摇摆条件下窄矩形通道内两相流动瞬态阻力特性研究
Research on Transient Flow Resistance of Two-phase Flow in Narrow Rectangular Channel in Rolling Motions
摘要
Abstract
The additional force arising from rolling motion causes the change of two-phase flow resistance .The characteristics of air-water mixture flow resistance in narrow rectangular channel (40 mm × 1.6 mm) in rolling motions were experimentally studied with the rolling periods of 8 s ,12 s ,16 s and the angles of 10° ,15° ,30° ,respectively . T he experimental results show that the transient frictional factor changes periodically . The larger the mass quality and the maximum rolling angle and the smaller the rolling period ,the larger the fluctuation amplitude of frictional pressure drop .A new correc-tion for predicting the transient frictional factor of two-phase flow in rolling motion is proposed with a good accuracy .关键词
