Hydraulic Fluid Mathematical Modeling
Applied Mechanics and Materials, 2013In hydraulic system, the property of hydraulic fluid will have non-linear behavior change when the temperature and pressure of fluid and the amount of dissolved and undissolved air vary, thus influencing the hydraulic system performance. The authors first studied the property of hydraulic fluid, and then constructed the mathematical expression ...

Hydraulic model investigations.
2020This 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.

Practical hydraulic turbine model
2006 IEEE Power Engineering Society General Meeting, 2006This paper reports on some practical hydraulic turbine models for Francis turbines and pumped-storage hydraulic turbines. The power system frequency during transient conditions greatly depends on governor control characteristics. Hydraulic governors take on an important role to stabilize a power system frequency.

Knowledge-Based Hydraulic Model Calibration
2003Le calage du modèle est une étape essentielle dans la modélisation d'un processus physique. Cet article décrit une approche pour l'assistance au calage de modèles qui combine méthodes d'optimisation et méthodes heuristiques. Notre approche utilise les techniques de systèmes à base de connaissances pour compléter les techniques classiques de ...

Conservation laws of mass, momentum and energy are used to describe open channel flow in sewers. The mass conservation principle yields the continuity equation, whereas Newton’s second law yields the momentum equation. Two flow variables in one-dimensional flow, such as the flow depth y and velocity V, or the flow depth y and the rate of discharge Q ...
