Abstract: Abstract In the petroleum production process, the tubing-casing annulus has been eccentric due to influence of gravity and thermal expansion, which complicates heat exchange. Forced convection heat transfer in vertical annulus with difference water-air ratios,… read more here.

Abstract: We use the ESPRESSO spectrograph at the Very Large Telescope to measure velocity shifts and gravitational redshifts of eight bona fide Hyades white dwarfs, with an accuracy better than 1.5 percent. By comparing the gravitational… read more here.
