It is studied that the formation mechanism of taylor bubble and its control method in gas - liquid two - phase flow, which affects the pressure balance and mechanical driving efficiency in the flow of petroleum engineering. experiments show that the formation of taylor bubble in gas - liquid two - phase flow is due to the intensive congregation and amalgamation of small bubbles driven by void fraction waves and that the highly turbulent flow is able to restrain this formation. thus, the flow regime transition may be checked by increasing the flow turbulence and controlling the disturbed frequency
對大管徑氣-液兩相流動中嚴重影響壓力平衡與機械驅動效率的段塞流生成機制和控制方法進行了研究,實驗證明段塞流的形成是由於空隙率波的大幅度增長使氣泡高度集中,並形成聚並所致。強湍流運動可以抑制taylor泡的形成。因此,通過強化湍流或控制擾動頻率可以對氣泡聚並起明顯的抑制作用。Principal conclusions were drawn as the following : the non compatibility of pressure or velocity of the gas on both sides of the contact surface is the cause of the formation of shock wave ; the heating effect of reflective shock wave to driving gas during charging or exhausting process is the internal mechanism of peak oscillating effect, and all the factors that influence the formation and the running of the shock wave will influence the peak oscillating frequency, cooling effect
