This paper describes the application of computational fluid dynamics to address the following problems in gas-liquid slug flow: (i) Effect of mixture velocity on slug tail propagation velocity and tail shape in horizontal slug flow; (ii) effect of tube inclination on slug propagation velocity; (iii) “bubble turning” in slug flow in a downward inclined pipe; (iv) effect of liquid viscosity on propagation and tail shape; (v) effect of gravity on propagation velocity; and (vi) effect of slug length on tail propagation velocity. All of the simulations were carried out using the Ansys CFX code, with tracking of the gas-liquid interface achieved using the volume of fluid technique. The flow conditions considered were within the turbulent regime, and for this, the standard k − ε model was used (although the influence of the turbulence model chosen was small). The calculated results compared favorably with experimental data, where such data is available.
