Abstract
Effect of density difference on dynamic behavior of swirling jets has been experimentally investigated in this work. When the density of inner jet is heavier than that of outer jet, stagnating flow becomes easier to be formed compared with that of iso-density flow, similarly to that reported in our previous work[3]. The location of stagnation point is lower than that of iso-density flow, which is clearly shown by velocity profile along the centerline of inner burner tube.
