description Slug flow is one of the most common flow patterns in the petrochemical industry. It will affect the normal operation of oil well surface pipelines and connected equipment, especially gas well multiphase flowmeters. The extant slug flow traps are complex in structure and limited in application sites. To reduce the influence of slug flow on gas-liquid two-phase measurement, a slug flow elimination device is designed based on the kinetic energy conversion method. The gas-liquid two-phase flow law inside the device and its energy loss are investigated using a combination of indoor experiments and numerical simulations. This study evaluates the device’s working performance, including the flow pattern, pressure fluctuation, velocity distribution, and energy loss. The results show that the flow rate and pressure fluctuation of the gas-liquid two-phase flow are weakened after the device. And the flow pattern changes from intermittent slug flow to gas-liquid continuous flow. The pressure drop calculation method for the device is developed based on the share of different structures in the total pressure drop, with a prediction error of 20%. The slug elimination device is designed to provide a flow pattern basis for metering equipment, improve metering accuracy, and further promote the development of multiphase metering technology.
