Hydrodynamic Calculations of the Movement of Two Phase Systems in Complex Pipelines

Based on hydromechanics of homogenous fluid and gas, a new model of two- phasesystems movement of fluid-gas type in horizontal tubes is suggested and the major calculationformula for the complicated development. This method enables us to define the mainparameters of the complicated pipelines considering the physical properties of two- phasesystems. The equation of two-phase systems movement in simple and complicated pipelines,allowing recommending using this approach in field experience is also obtained.
