Liquid-Liquid Displacement in a Horizontal and Inclined Pipe Section

In this paper experimental results from liquid-liquid displacement experiments are presented. Four scenarios, flushing oil with water and flushing water with oil, in a horizontal and downward inclined test section, respectively, were tested at different flow rates. The transparent test section of 15 m length and 60 mm ID allowed for visualization of the flushing front. The flushing front propagation velocity was measured by conductivity ring probes. The liquids were tap water and a mineral oil with a viscosity of 60 cP. The experimental results are compared with the commercial flow simulator OLGA.
