对不同结构的波瓣混合器的射流混合进行了数值研究。通过对流向涡流内的传热传质研究，以及正常涡环的“拉伸”和“切割”，对波瓣射流混合的研究提出了建议。在综合研究流体力学和传热传质的基础上，提出了一种更合理的波瓣射流混合机理。不同结构的波瓣混合器在流体力学和传热传质方面的不同意味着不同的机理。
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.
