| Zusammenfassung | Hot free jet flow is an important process in risk assessment and explosion protection in various ranges of application. The numerical study on nonreactive jets with fully developed turbulence and density variations were performed using different turbulence models. As expected LES simulations give best result but are highly time-consuming. When the parameter of the SAS model will be adapted to the free jet problem SAS could be a feasible alternative with smaller expense. The lower resolution of URANS models may be sifficient for problems with moderate Reynolds number. In accordance with the measurements based on LIF technique numerical simulations characterize a pulsed helium free jet injected in nitrogen. A moderately turbulent flow is evaluated by URANS simulations conform to measurement data. |
