Abstract Power generation from intermittent renewable energy resources (e.g. wind, solar) requires regulation of the electric grid. Although most hydraulic turbines are designed to work in their best efficiency points, nowadays they being used more often under varying operating conditions stabilize Unstable and fluid flow during transient operation cause significant pressure fluctuations load v...

"Three-dimensional Bayesian geostatistical aquifer characterization at the Hanford 300 Area using tracer test data" (2012). US Department of Energy Publications. Paper 309. [1] Tracer tests performed under natural or forced gradient flow conditions can provide useful information for characterizing subsurface properties, through monitoring, modeling, and interpretation of the tracer plume migrat...

Today, pipe systems are the most common facilities to convey various fluids from one place to another. In such facilities faults like leaks lead to advert consequences such as economic losses and social health threats. The fact that early detection of leaks can play a prominent role in reducing the amount of these undesired impacts has absorbed noticeable attention from researchers to this fiel...

A new method for the simulation of gas turbine fuel systems based on an inter-component volume method has been developed in this study. It is able to simulate the performance behaviour of each of the hydraulic components including pumps, valves, metering unit, etc. of a fuel system using physics-based models, which potentially offers more accurate results compared with those using transfer func...

Inverse solution techniques currently used for estimating unsaturated soil hydraulic functions from laboratory outflow experiments use cumulative outflow only in combination with initial and final soil water pressure head values. Additional soil water information is needed to improve the estimation procedure and to minimize uniqueness problems. It was the objective of this study to experimental...

A range of continental-scale soil datasets exists in Europe with different spatial representation and based on different principles. We developed comprehensive pedotransfer functions (PTFs) for applications principally on spatial datasets with continental coverage. The PTF development included the prediction of soil water retention at various matric potentials and prediction of parameters to ch...
