Research on the energy characteristics of the turning region in the cavitation performance curve of an axial flow pump based on energy flow density and entropy production

Engineering Applications of Computational Fluid Mechanics
Cavitation significantly impacts the performance and stability of axial flow pumps, yet the underlying mechanisms driving head rise in the cavitation curve remain inadequately understood.

Collisional energy loss of heavy quarks

, 2013
We develop a transport approach for heavy quarks in a quark-gluon plasma, which is based on improved binary collision rates taking into account quantum statistics, the running of the QCD coupling and an effective screening mass adjusted to hard-thermal ...

Energy loss in high energy heavy ion collisions from the Hydro+Jet model [PDF]

, 2002
We investigate the effect of energy loss of jets in high energy heavy ion collisions by using a full three-dimensional space-time evolution of a fluid combined with (mini-)jets that are explicitly evolved in space-time.

“N‐π‐N” Type Oligomeric Acceptor Achieves an OPV Efficiency of 18.19% with Low Energy Loss and Excellent Stability

Advanced Science, 2022
A novel “N‐π‐N” type oligomeric acceptor of 2BTP‐2F‐T, constructed by two small non‐fullerene acceptor (NFA) units linked with a thiophene π bridge is reported. The 2BTP‐2F‐T not only combines the advantages of small NFA and polymeric acceptors (PYF‐T‐o)

Planning and Design of a PV-Battery Microgrid System for Improving the 22 kV Radial Distribution System of the Sichang Island in Thailand [PDF]

E3S Web of Conferences, 2020
Voltage drop and energy loss issues in remote areas will degrade the reliability of power system when loads are subsequently increased. This paper aims to design a PV-Battery microgrid system to enhance the performance of the 22 kV radial distribution ...

Parton energy loss in QCD matter

, 2017
QCD jets, produced copiously in heavy-ion collisions at LHC and also at RHIC, serve as probes of the dynamics of the quark-gluon plasma (QGP). Jet fragmentation in the medium is interesting in its own right and, in order to extract pertinent information ...

Compositional analysis of InAs-GaAs-GaSb heterostructures by low-loss electron energy loss spectroscopy [PDF]

, 2013
As an alternative to Core-Loss Electron Energy Loss Spectroscopy, Low-Loss EELS is suitable for compositional analysis of complex heterostructures, such as the InAs-GaAs-GaSb system, since in this energy range the edges corresponding to these elements ...

DYNAMICS AND ENERGY LOSS IN SUPERBUBBLES [PDF]

The Astrophysical Journal, 2014
Interstellar bubbles appear to be smaller in observations than expected from calculations. Instabilities at the shell boundaries create three-dimensional ef- fects, and are probably responsible for part of this discrepancy. We investigate instabilities and dynamics in superbubbles by 3D hydrodynamics simulations with time-resolved energy input from ...

Financial Burden Associated With Hospitalisation Among Families of Childhood Brain Tumours in Australia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Families of children with cancer experience significant financial strain, even with universal healthcare. Indirect costs, such as productivity losses and non‐medical expenses, are rarely included in economic evaluations, and little is known about how effectively financial aid programmes alleviate this burden. Childhood brain tumours

Heavy Quark Production and Energy Loss

, 2012
Heavy flavor research is a vigorous and active topic in high-energy QCD physics. Comparing theoretical predictions to data as a function of flavor provides a unique opportunity to tease out properties of quark-gluon plasma. We explicitly demonstrate this
