Sinopsis

Experimental and numerical study of slug flow dynamics in inclined pipes for gas-liquid and gas-liquid-solids systems were performed. Measuring of slug flow speed was made by using time-of-flight method. For speed measurements video recordings of slug flow dynamics were used. Experimental data about slug flow speed in different conditions were obtained. Non monotonic dependence of slug flow speed in granular layer vs angle of pipe inclination was shown. Adding solid particles shifts the maximum of slug speed to greater inclination angles of pipe relatively to the horizontal plane. Slug flow speed in packed beads can be greater or less than in pure liquid, depending on diameter of beads. Small diameters of beads lead to choking of slug flow. Model of slug flow in granular layer, based on lattice Boltzmann method, was developed. For numerical simulations graphical processor nVidia Tesla C2075 was used. Numerical results are in agreement with experimental studies.
