Abstract
The aim of this study is to
investigate numerically the effects of four vortices on the dynamic,
scalar, and turbulent fields of the hydrogen jet. These vortices, which
appear in the vicinities of the nozzle, are created by
the vortex generators (VGs), and they are assembled with periodicity or
symmetry in order, respectively, to give four vortices of the same or opposite direction. A second-order
Reynolds stress model is used to investigate asymmetric turbulent jet.
The results indicate that the presence of the vortex near
the emission jet section noticeably enhances mixing to ensure a good
combustion.
