查询词典 vortexes

Then, a series of successful numerical simulations on the finite length inclined positively buoyant jets in uniform cross flows environment are developed. Based on the results from numerical simulations, some qualitative pictures of the complex three -dimensional mean flows are given. In terms of these pictures, the flowing behavior of the buoyant jets and the mechanism of end-vortexes generation are made a study. The change rules of end-vortexes and temperature and dilution on trajectory of jets, horse-hoof shape of buoyant jets on horizontal, the phenomenon of the jets touch wall, and the effects of diffuser length^ densimetric Foroude number % velocity ratio on buoyant jets are also given.
