Hydraulic Jump Model and Programming in Visual Basic

摘要

The work is aimed at modeling the rise in water level in a flow, especially, in open channels as a result of abrupt change in flow regimes from unstable shooting flow to a relatively stable streaming flow. The cumbersomeness of manual computation of hydraulic engineering problems that involve so much iterations that led to waste of time and cost were modeled for optimal maximization of profit. The methodology involves combination with energy and momentum equations, and the mathematical model determined the engineering characteristics of the hydraulic jump. The equations of the model were simulated with visual basic programming language. A case study on the model showed that the programme runs perfectly and comparison of the results of the experiments with the manual results showed that both gave same result of 100% The results of the experiments enhanced irrigation, water supply, mix chemicals for water purification, aerate water and waste water for water treatment and removal of air bubbles in supply lines. It is recommended that the programme be used for analysis, design and consulting in engineering services.
