Tribological behaviors of laser textured surface under different lubrication conditions for rotary compressor

open access: yesScientific Reports, 2023
Tribological behaviors of laser textured surface with elliptical dimples were experimentally compared with that of the smooth one under different lubrication conditions, including the poor-oil, rich-oil and dry lubrication.

A new method to suppress the MHD instability of cylindrical liquid metal batteries [PDF]

open access: yesE3S Web of Conferences, 2023
The magnetohydrodynamics (MHD) instabilities of liquid metal batteries (LMBs) severely limit the wide application and commercialization of LMB. A new technology is proposed, which is called the gridstructure (GS), so as to achieve the suppression effect ...

On the definition of energy for a continuum, its conservation laws, and the energy-momentum tensor [PDF]

open access: yes, 2016
We review the energy concept in the case of a continuum or a system of fields. First, we analyze the emergence of a true local conservation equation for the energy of a continuous medium, taking the example of an isentropic continuum in Newtonian gravity.

Influence of Particle Size Distribution on the Physical Characteristics of Pore-Filling Hydrate-Bearing Sediment

open access: yesGeofluids, 2021
Nature gas hydrates (NGHs) are regarded as a potential alternative energy source due to their huge reserves and wide distribution. According to the geophysical surveys, the pore-filling hydrates occupy a large proportion of the global hydrate reserves ...

Energy Conservation and Hawking Radiation

open access: yes, 2004
The conservation of energy implies that an isolated radiating black hole cannot have an emission spectrum that is precisely thermal. Moreover, the no-hair theorem is only approximately applicable.

Weber-like interactions and energy conservation [PDF]

open access: yes, 1997
Velocity dependent forces varying as $k(\hat{r}/r)(1 - \mu \dot{r}^2 + \gamma r \ddot{r})$ (such as Weber force), here called Weber-like forces, are examined from the point of view of energy conservation and it is proved that they are conservative if and
