• Effects of Injection Rate on Flow and Mixing Process in an Unsteady Jet

抄録

Gas flows in unsteady jets were calculated from a large eddy simulation (LES), and the effect of the initial injection-rate on flows and mixing process were investigated. Obtained results show that in the case that the injection speed rises slowly, the intensity of initial vortex-ring is low and the growth of turbulence is suppressed. As the result, turbulence mixing is also suppressed and local high-density spots are observed even in the downstream.
