The potential for photovoltaic-powered pumped-hydro systems to reduce emissions, costs, and energy insecurity in rural China
(Elsevier, 2021-09)
Article
Open AccessHomes in rural China often have access to water wells for domestic and agricultural use. Given the significant difference in height between the well water and the roof of the house, such an arrangement could be used as a ... -
Exploring the Regulation Reliability of a Pumped Storage Power Plant in a Wind–Solar Hybrid Power Generation System
(2021-09-17)
Article
Open AccessIn the coming decades, the proportion of wind–solar energy in power system significantly increases, resulting to uncertainties of power fluctuation in abundant wind–solar energy regions. The flexibility operation of Pumped ... -
Combination of acoustic emission and vibratory measure-ments to characterize an ultrasonic vibration assisted ball burnishing tool for a lathe
(2021-07-14)
Article
Open AccessIn this paper, a resonant system that produces a movement of low amplitude and ultrasonic frequency is used to achieve the vibration assistance in a ball-burnishing process. A full vibration characterization of this process ... -
Dynamic transitions of the magnetized spherical Couette flow between its base state and the return flow instability
(Institute of Physics (IOP), 2022-01-01)
Article
Open AccessThe transition between the stable base state of the magnetized spherical Couette (MSC) flow and the return flow instability is experimentally investigated. The experiments are conducted using an MSC setup consisting of ... -
Box-Jenkins autoregressive models for PEMFC operating under dynamical conditions
(2021)
Conference report
Open AccessThe objective of the present work is to explore and validate autoregressive, control oriented models models Proton Exchange Membrane Fuel Cells coperatinf under dynamic condditions. Autoregressive models have several ... -
On the use of vibrational hill charts for improved condition monitoring and diagnosis of hydraulic turbines
(2022-01-22)
Article
Open AccessTo cope with the intermittent power supply of the new renewable energies and demand fluctuations, Francis turbines are required to operate more and more in an extended operating range, far away from the design point. With ... -
Abnormal pulmonary artery bending correlates with increased right ventricular afterload following the arterial switch operation
(2019-09)
Article
Open AccessPurpose: In transposition of great arteries, increased right ventricular (RV) afterload is observed following arterial switch operation (ASO), which is not always related to pulmonary artery (PA) stenosis. We hypothesize ... -
Energy preserving turbulent simulations at a reduced computational cost
(2015-10)
Article
Open AccessEnergy-conserving discretizations are widely regarded as a fundamental requirement for high-fidelity simulations of turbulent flows. The skew-symmetric splitting of the nonlinear term is a well-known approach to obtain ... -
An efficient time advancing strategy for energy-preserving simulations
(2015-08)
Article
Open AccessEnergy-conserving numerical methods are widely employed within the broad area of convection-dominated systems. Semi-discrete conservation of energy is usually obtained by adopting the so-called skew-symmetric splitting of ... -
Approximate projection method for the incompressible Navier–Stokes equations

Explicit Runge–Kutta schemes for incompressible flow with improved energy-conservation properties
(2017-01)
Article
Open AccessThe application of pseudo-symplectic Runge–Kutta methods to the incompressible Navier–Stokes equations is discussed in this work. In contrast to fully energy-conserving, implicit methods, these are explicit schemes of order ... -
A numerical aerodynamic analysis on the effect of rear underbody diffusers on road cars
(Multidisciplinary Digital Publishing Institute, 2022-04-01)
Article
Open AccessThe aerodynamic complexity of the underbody surfaces of conventional road vehicles is a matter of fact. Currently available literature is focused mainly on very simple Ahmed-body geometries as opposed to realistic car ...
