Suggestions on investigations of lobed jet mixing

Jet mixings of different constructional lobed mixers comprised of lobed nozzles with and without a mixing duct were investigated numerically. Based on the heat and mass transfer investigation in the streamwise vortices and the stretch and cut of the normal vortex ring, suggestions on investigations of lobed jet mixing were provided. A more reasonable mechanism for lobed jet mixing was suggested to be revealed when combined fluid dynamics and heat and mass transfer were being investigated. Differences in fluid dynamics and heat and mass transfer with different constructional lobed mixers meant different mechanisms. (C) 2019 Elsevier Masson SAS. All rights reserved.
