Abstract: This paper presents results of an experimental and theoretical study on the use of a high density polyethylene (HDPE) additional pipe inserted downstream of a pump in a hydraulic network as a surge suppressor. The experiments ...

Abstract: The paper proposes the evaluation of unsteady friction by a one-dimensional local balance model. The model is applied for the case of water hammer in a single pipeline for both the downstream end and upstream end valve, ...

Abstract: The paper presents the results of the calibration, by means of a microgenetic algorithm, of the mechanical parameters of high-density polyethylene pipes, to reproduce experimental unsteady flow runs in an installation ...

Abstract: The paper examines the problem of prediction of uniform turbulent flow in a compound channel with the nonlinear

Abstract: A quasi-two-dimensional model for unsteady-flow analysis in pipes and pipe networks is presented. The turbulence model is based on the mixing length hypothesis in the turbulent zone and on Newton's law in the viscous ...

Abstract: This note considers the evaluation of resistances in unsteady flow by means of a 1D unsteady friction model. The model is applied for the case of a water hammer, both in a single gravity pipeline and in a single pumped ...
