One model for gas liquid transmission in the major pipelines

The paper describes the variant of the hybrid numerical model allowing us to assess the parameters of nonsteady anisothermic transmission of gas liquid media in the networks of ramified major pipelines with the high extent of adequacy to actual physical processes. This model is oriented to the application in the calculated cores of high-accuracy computer hydraulic simulators, which are used for the support of dispatcher problem-solving in the gas and oil industry. The model is also well-recommended itself in analyzing the operation of the pipeline networks in atomic power and heat power plants. The model structure is suggested to be numerically analyzed by the grid methods. The empirical coefficients are determined in the manufacturers of the fuel-energy complex.
