Low-Dimension Robust Computational Algorithm for a Linear Distributed Parameter Water Hammer Model

Water hammer is a hydraulic phenomenon occurring in cases of sudden load drop e.g. hydraulic turbine shutdown. These undesirable events lead to fast transients processes which require taking into account the distributed parameters. As a system with distributed parameters, the most realistic mathematical model of the water hammer phenomenon is that described by hyperbolic Partial Differential Equations. The qualitative evaluation of this phenomenon is performed by means of its computational model obtained by using a loworder robust computational algorithm previously introduced. Simulated experiments are discussed from the points of view of the engineering problem as well as of the numerical approach.
