Abstract:
This paper presents a new numerically efficient implementation of flow mixing algorithms in dynamic simulation of pipeline fluid transport. Mixed characteristics include molar mass, heat value, chemical composition and the temperature of the transported fluids. In the absence of chemical reactions, the modeling is based on the universal conservation laws for molar flows and total energy. The modeling formulates a sequence of linear systems, solved by a sparse linear solver, typically in one iteration per integration step. The functionality and stability of the developed simulation methods have been tested on a number of realistic network scenarios. The main output of the paper is a functioning and stable implementation of flow mixing algorithms for dynamic simulation of fluid transport networks.
