The purpose of this paper is to present a fast nonlinear solver for the prediction of transients in network flows.
Broyden method‐based nonlinear solvers are developed to solve the system of conservation equation for fluids by judiciously exploiting physical coupling among the equations.
To demonstrate the feasibility and robustness of the solvers, two test cases of practical engineering interest were solved. The results obtained by the solvers were verified against analytical results for a simplified case. The performance of the solvers was found to be comparable or better than existing solvers.
The proposed solver enables predictions of fluid and thermal transients in complex flow networks feasible in reduced computational time.
