Numerical study, investigation effect of distance and angle of spur dike on average velocity distribution and maximum velocity position at mild 90 degree bend
Use the Spur dike as one of the easiest ways to protect the costal of the river has always been of interest to River engineers.The aim of this study was numerical investigate, the effect of distance and angle of the spur dikes parameters on the pattern of distribution of average velocity and the location of maximum velocity position at a mild 90 degree bend. For this purpose used ANSYS CFX so...
متن کاملVertical Velocity Distribution in Open-Channel Flow with Rigid Vegetation
In order to experimentally investigate the effects of rigid vegetation on the characteristics of flow, the vegetations were modeled by rigid cylindrical rod. Flow field is measured under the conditions of submerged rigid rod in flume with single layer and double layer vegetations. Experiments were performed for various spacings of the rigid rods. The vegetation models were aligned with the appr...
متن کاملOptimization of the Geometric Parameters of the Protective Spur Dike using Taguchi Method and GRA.
In general, engineering designs need to optimize the factors affecting the under-study phenomenon; however, this is often a costly and time-consuming process. In this regard, new methods have been developed to optimize with fewer tests; thus, they can make the whole process more affordable. In this study, Taguchi and Taguchi-GRA methods were used to design the geometric parameters of the protec...
متن کاملNumerical Study on the Effect of Ratio among Various of Submersion on Three Dimensional Velocity Components around T-shaped Spur Dike Located in a 90 Degree Bend
Spur dike is one of the hydraulic structures used in rivers to protect river banks. In this paper, flow pattern around a T-shaped spur dike which is located in a 90◦ bend and different amounts of submersion has been studied using Flow-3D. Numerical results have been compared with experimental results and have been analysed.
متن کاملتأثیر قدرت جریان ثانویه بر تنش برشی بستر پیرامون آب‌شکن سرسپری مستقر در موقعیت‌های مختلف قوس 90 درجه با بسترصلب
In this study, the effect of the secondary flow strength and vorticity on variations of bed shear stress for different positions of spur dike are compared through a mild 90˚ bend along with a T-shaped spur dike in a rigid bed. To carry out these experiments, three dimensional velocimeters (ADV) have been used for measuring velocity. Moreover, a comparison has been made between velocity vectors ...
