Abstract
It is difficult to express a fully turbulent developing process involving generations, interactions and disintegrations of vortex loops. Because it is actually impossible to express the inlet condition of simulation as well as experiment. Particularly, initial region of jet is open to that's effect. If to make target near region such as material processing, therefore, disagreement between experiment and calculation is fatal problem. In this paper, it is purpose to investigate set-up method of inlet turbulence condition making generations, interactions and disintegrations of vortex loops and to apply this method to hydrogen diffusion jet flame.
