... multiple issues like accumulation of particles and under-deposit corrosion. Experiments are performed at extremely low sand concentrations for both liquid-sand (single phase) and gas-liquid-sand (multiphase) flows to determine the critical flow rates necessary to keep sand moving in horizontal lines...

... ABSTRACT An experimental study was conducted to investigate the effect of particle size on the critical velocity and near wall turbulence characteristics of water flow over the sand bed deposited in a horizontal pipeline. Industrial sands of four mesh sizes (20/40, 30/50, 40/70, 100) were used...

... the flow cross sectional area and creating an insulating hydrate layer, in the first case; by precipitating solid particles and forming a dispersion flow, in the second case (3). In both situations, pipe blockage may happen if hydrate formation is out of control, being by a complete obstruction...

... solid particle erosion in multiphase flow is difficult as so many factors are involved in the problem. Currently, both experimental and numerical approaches can be applied to investigate the phenomenon of multiphase flow erosion. Several experimental studies were conducted at the University of Tulsa...

... Abstract This paper examines the critical flow rates of gas and liquid necessary to keep particles moving in a horizontal flow line with emphasis on flows with high gas-liquid ratios resulting in stratified flow with small liquid hold-up. Experimental results are presented for flows in 0.05 m...
