The calculation of air-entrainment distribution in open-channel flow

Abstract

     The calculation of air entrainment distribution within an exposed flow will make it a background to determine properly height of channel wall, to check cavitation conditions in its bottom and lateral walls of the flowing channel, to calculate the length of the jet trajectory, etc ... In this article, background and basis on which the equation to calculate the air entrainment distribution within an exposed flow was established are described and explained. A corresponding programme has been also established and applied, see example shown at the end of this article. The said methodology and programme have been recommended for application in calculating exposed flow having high velocity.
