AI Technical Summary
When existing one-dimensional simulation technology is extended to pipeline networks, there are problems such as difficulties in connection processing and unreasonable assembly of equation sets, which limit its application in large-scale pipeline transportation systems.
By employing staggered mesh generation and local-global mesh mapping, combined with the finite volume method to discretize the mass, momentum, energy, and pressure equations of gas-oil-water three-phase flow, an efficient global linear equation set is assembled. These equations are then solved using a semi-implicit algorithm and subspace iteration method, achieving high-precision and efficient simulation of transient multiphase flow in pipeline networks.
It improves simulation accuracy while maintaining the fast computation speed and robustness of one-dimensional simulation, breaking through the application limitations in large-scale pipeline networks and making it suitable for transient simulation of large-scale pipeline transportation systems.
