The paper presents the calculation of the liquid mixture outflow consisting of two components - water and oil simulator (Exxsol D100), passing to the liquid separator of a multiphase test bench. The hydrodynamics of the liquid flow development influences the quality of its separation - the complete separation of components, since the process of a gas-liquid mixture reproduction supposes the invariability of its main parameter - moisture content. This indicator is important for testing, verification and calibration of multiphase flow meters, which have recently become widespread in measuring the flow rate of oil and gas water wells, especially on offshore platforms of shelf fields. When designing a separator in the entire flow rate range, the hydrodynamic calculation of the initial section of the jet development will make it possible to determine its structural dimensions to intensify the separation process to the most complete separation of the components of the liquid mixture, which is important when they are fed separately in a multiphase test bench in front of the measuring section. This problem is especially relevant in the design of separators operating on the gravidynamic separation principle, which is typical for the majority of similar technological devices used.
