Abstract: Abstract Outwardly-opening injectors for gasoline direct-injection engines generate hollow-cone sprays which have better atomization performance than conventional hole-type nozzle sprays. The ambient density alters the initial flow breakup and the downstream vortex structure of the… read more here.

DOI: 10.1093/mnras/sty2617
Abstract: Galactic outflows are now commonly observed in starburst and active galactic nuclei (AGNs) host galaxies. Yet, there is no clear consensus on their physical driving mechanism(s). We have previously shown that AGN radiative feedback, driven… read more here.
