Mass and charge transport in micro and nano-fluidic channels [PDF]

open access: yes, 2006
We consider laminar flow of incompressible electrolytes in long, straight channels driven by pressure and electro-osmosis. We use a Hilbert space eigenfunction expansion to address the general problem of an arbitrary cross section and obtain general ...

An Energy-Saving Scheme to Reduce Throttling Losses in Hydraulic Excavators Based on Electro-Hydraulic Energy Storage

open access: yesIEEE Access
The enormous throttling losses are the crucial reason for the low energy efficiency of non-road mobile machinery. To achieve energy saving, a parallel electro-hydraulic hybrid drivetrain that combines an electric-hydraulic energy recovery system with a ...

Gain scheduling linear model of an electro-hydraulic actuator

open access: yesAn International Journal of Optimization and Control: Theories & Applications (IJOCTA), 2017
In different industrial processes in which position and force control are desired, electro-hydraulic systems have a widespread area of utilization. Models of electro-hydraulic systems include high order nonlinearity. In this study, a gain scheduling linear model corresponded with nonlinear model of a hydraulic force actuator system is developed.
