Abstract:
Considering the realistic transient flow in complex branch-like pipeline network, we have presented for the first time the mathematical model of initial-boundary value problem in the system of partial differential equations of pressure distribution. We have proved the solution of the initial-boundary value problem to be existent and unique by the semigroup theory of linear operators, and obtained the wide-sense solution by the operator series method.
Key words: Network design, Mathematical model, Transient flow, partial defferential equations, Wide-sense solution
