  • Aiming at the difficulties of gas-liquid flow experiment in the vertical pipe,the modeling and simulation methods were conducted to investigate the dynamic model of slug flow and the rising velocity of Taylor hydrogen bubble in upward vertical slug flow.Simulation results show that the velocity of the developed Taylor hydrogen bubble is 0.2265m·s-1.In flowing liquid,the velocity coefficient is insensitive to the liquid Reynolds number.As the Reynolds number based on the liquid velocity,the Reynolds number increases from 220 to 6400,and the velocity coefficient decreases from 1.83 to 1.14.In developing Taylor bubble,the rising velocity increases with the shortening distance between consecutive bubbles.
