Comparison of Experimental Study and Cfd Analysis of the Flow under a Sluice Gate
Flow in the open channels has great importance in the hydraulic engineering. Any disturbances as contractions and expansions affect the flow characteristics like velocities, flow rates and water surface profiles. Their effects on the flow must be considered during the design process of flow structures. In the last decades numerical solutions become popular as experimental studies take time, may...
متن کاملThe effect of disturbances on the flows under a sluice gate and past an inclined plate
Free surface potential flows past disturbances in a channel are considered. Three different types of disturbance are studied: (i) a submerged obstacle on the bottom of a channel; (ii) a pressure distribution on the free surface; and (iii) an obstruction in the free surface (e.g. a sluice gate or a flat plate). Surface tension is neglected, but gravity is included in the dynamic boundary conditi...
متن کاملData Flow Analysis and Optimisation Potential from Gate - to - Gate
In the framework of the Joint Air Navigation Experiments (JANE) programme, a business process model of the current Air Traffic Management (ATM) processes was developed. A common understanding and process view among all involved organisations (Air Traffic Control, Airline, Airport) was achieved. The business process model considers the activities as being carried out by different departments of ...
متن کاملمطالعه جریان همزمان از زیر یک دریچه کشویی و روی یک سرریز لبه تیز ذوزنقه‌ای
The combined system of gate and weir is used for flow measurement in open channels. But in case the passing water has floating material and sediment it damages their performance and hence error of measurement will increase. In order to solve this problem, weir and gate can be combined and a concentrated hydraulic system known as weir-gate can be developed, thus allowing sediments transportation...
متن کاملNumerical Solution for Gate Induced Vibration Due to Under Flow Cavitation
Among the many force s to which hydraulic structures are exposed to, the forces induced by cavitation incident are of typical hydrodynamic unknown forces. The aim of this study is to define these forces as coupled fluid-structure interaction under two dynamic effects. The first dynamic effect which incorporates facilities for dealing with cavitation fluid is based on the appearance and bursting...
