Conduit transportation of two-phase and three-phase flow is applied as one of the transportation methods. Slug flow is generated when gas-liquid is mixed simultaneously in a conduit. This flow can transport the solid and material with high viscosity. The feature of this slug flow is that it generates a high-speed intermittent turbulent flow and it is a complex current with a pressure fluctuation affected by flow energy loss. Therefore, it is expected to have applications in many engineering fields like processing of colony algae, collection of methane hydrate in sea bottom and the sterilization of ballast water in tankers that use ozone gas. In this paper, we examined the fluidity characteristics of slug flow, acceleration loss due to the liquid film and prediction of initial pressure was investigated for gas-liquid slug flow generation which is being considered for future use in long distance horizontal pipe where the compressibility of the gas became remarkable.
