In order to probe into the penetrability of a turbulent jet in cross-flow (JICF) as well as its characteristics of the flow field, large eddy simulation (LES) and standard k-εturbulence model were employed separately to simulate a round turbulent jet in cross-flow with the velocity ratio of 10, the Re based on the jet velocity 50m/s is 16600.

Using the quasi-high speed image collecting technology and the digital image processingtechnique, the clear image sequences of 2-dimension large scale coherent vortex structure inshearing boundary layer of turbulent jet and diffusion flame were acquired.

The two different models,a presumed PDF model(Model Ⅰ)and a joint mixturefraction-turbulent frequency PDF transport model(Model Ⅱ),are coupled with the laminar flamelet modelto predict turbulent jet diffusion flame structure of methane/air.

In accordance with the problem of the thermal pollution in shallow water cooling pond, a numerical model of coupling of near-region-turbulent-jet-flow and far-region-circulation flow is put forward herein.
