Erratum to “Effects of injection angle and pressure on mixing performance of fuel injection via various geometries for upstream-fuel-injected scramjets” [Acta Astronautica 128 (2016) 485–498](S0094576516304052)(10.1016/j.actaastro.2016.08.008)

The authors regret that an error was identified in the expression of the mixing vorticity efficiency defined in Eq. (5) of the article. The correct expression is [Formula presented], where the effective injector diameter D must be in the numerator rather than in the denominator according to dimensional analysis. The author regrets this error, while the correct definition was used for the calculation of mixing vorticity efficiency in the study, and so this correction does not affect the results, discussions, or conclusions. The authors would like to apologise for any inconvenience caused.
