  • In order to obtain empirical correlations of jet penetration for engineering application, a empirical mixing model for the analysis of transverse gaseous jet in supersonic flow was investigated by modeling the jet centerline, penetration boundary and injection's spanwise distributional characteristics. Several experimental cases were used to verify the performance of the present model. Results indicate that, within the momentum flux ratio of 0.5-5.3, the present model agreed well with the experiment image both in the jet centerline and penetration boundary, and in the area near jet centerline, the model predicted a injection mole fraction with an error less than 5%, which shows a higher precision in contrast with the existing models. With the increasing of the momentum flux ratio, the counter-rotating vortex pairs are strengthened in the near region downstream of the injector, which leads to some inaccuracy of spanwise mole fraction distribution calculated by the present model. This indicates that the present model validity is affected by the momentum flux ratio and downstream distance.
