Correction: Physical insight into fuel-air mixing for upstream-fuel-injected scramjets via multi-objective design optimization (Journal of Propulsion and Power, (2015), 31, 6, (1505-1523), 10.2514/1.B35661)

This correction pertains to an error in the expression of the mixing vorticity efficiency defined in Eq. (7) in the original article when it was first published online [http://arc.aiaa.org/doi/abs/10.2514/1.B35661]: 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.
