Experiment Investigation on Onset of Flow Instability in Narrow Rectangular Channel under Low Pressure and Low Mass Flux Condition
摘要
Abstract
The visualized experimental investigations were carried out on the phenomena of onset of flow instability (OFI) at low pressure and low mass flux condition in a verti‐cal narrow rectangular channel with the section of 40 mm × 3 mm .The bubble behavior and flow pattern distribution at OFI were visualized and then the mechanism of OFI was analyzed qualitatively .The effects of thermal‐hydraulic parameters on OFI were pre‐formed .Based on the experimental data ,existing OFI predicted correlations were evalu‐ated .T he results show that the correlations ,w hich adopt the parameters at saturation point as the independent variables ,can predict the experimental data reasonably .关键词
