Abstract:The characteristics of the air water two phase flow often occurred in hydraulic engineering are analysized in this paper so as to establish the mathematical model of the flow. Also a two fluid model has been given, which can be used to calculate "dilute bubbly flow" in hydraulic engineering. And the air water two phase flow in open channel was calculated to test the model. The computational air concentration is compared with experimental data, and they are in agreement with each other.
Keywords:air  water two  phase flow  two  fluid model  dilute bubbly flow
