NUMERICAL SIMULATION OF AERATED JET

摘要

Aerated jet, such as the jet flow behind the flip bucket of the overflow dam, widely exists in hydraulic engineering. Until now model test and prototype observation are the two main methods to study this aerated jet for a special hydraulic project. In this paper a 3-D mathematical model for the aerated jet was firstly suggested, and the trajectory as well as the energy dissipation rate of the aerated jet were also discussed. By comparison with the results of model test and prototype observation data it seems that our suggested model has high predictive power, which is very useful in the study of energy dissipation and jet flow atomization problems.
