Hydraulic model investigations. [PDF]

open access: possible, 2020
This thesis is based upon the work and experience of the author since 1956. During this period he has been engaged in the design, construction and operation of hydraulic models, first as an engineer employed by the Department of Public Works, N.S.W. and then as a Lecturer in Civil Engineering in the University of Queensland.

New Hydraulic System Modelling

Journal of Vibration and Control, 2004
The efficient design of hydraulic systems requires fast simulation methods. In most simulation programs, the hydraulic components are coupled by compressible joints. Since the compressibility of oil is very small, this leads to stiff differential equations.

Accurate Dynamic Modelling of Hydraulic Servomechanisms

2019 Design, Automation & Test in Europe Conference & Exhibition (DATE), 2019
In this paper, the process of modelling and identification of a hydraulic actuator is discussed. In this framework a simple model based on the classical theory has been derived and a first experimental campaign has been performed on a test bench. These tests highlighted the presence of unmodeled phenomena (e.g. dead-zone, hysteresis, etc.), therefore a

Modeling for Hydraulic Capacity

Journal AWWA, 2004
Pipes in distribution systems often become tuberculated because of internal corrosion, sliming, and scaling. This condition frequently leads to an increase in the roughness of the pipe wall and in a reduction of the pipe diameter. Such changes lead to reduced hydraulic capacity of the pipes within distribution systems.
