Solution of Flow Field Equations and Verification of Cavitation Problem on Spillway of the dam
The main objective of this paper is to formulate a mathematical model for finding flow field and cavitation problem on dam spillways. The Navier-Stokes Equation has been applied for the computation of pressure and velocity field, free water surface profiles and other parameters. Also, for increasing accuracy of the problem, viscosity effect has been considered. Because of internal flows the eff...
متن کاملNumerical Investigation of Cavitation on Spillways. A Case Study: Aydoghmush dam
Cavitation is among the most complicated and common damages of spillway structures. This phenomenon is controlled by different parameters including the pressure, flow velocity, spillway surface material, operation time, and air flow content. The cavitation index is calculated along the spillway and compared with its critical value using the measured values of the flow’s hydraulic parameters. Th...
متن کاملInternal erosion under spillway rested on an embankment dam
In this paper we investigate the mechanism of internal erosion caused in the right abutment of the Shahghasem dam’s spillway. Shahghasem dam is an earthen dam located in Yasouj, in southwest of Iran. A significant hole and pipe have been observed in the corner of the right abutment from upstream view. The foundation is Marlstone, which has low cohesion and susceptible for internal erosion and p...
متن کاملInvestigation of Cavitation Damage Levels on Spillways
This paper presents a classification of cavitation damage levels on spillway surface. Two important factors influencing cavitation damage have been considered in this study, flow velocity and cavitation index. Based on these factors, five different damage levels from no cavitation damage to major cavitation damage have been determined. The method was applied to data of the Shahid Abbaspour dam ...
متن کاملReduce the maximum scour depth downstream of Flip Bucket Spillway through the spillway geometry optimization (study released spillway dam Kurdistan)
The Performance of shooting pool, in addition to the quality of the area in which the flow collides with it, depends to the height of the jet drop, the angle of the water flow, the depth of the jet and the concentration of the jet. By increasing the height of the jet drop, the fall velocity increases and subsequently the jetchr('39')s energy will be more intrusive. Different collision area from...
