Application of ANSYS-Fluent Software for Innovative Stepped Dissipation Blocks Arrangement in Ogee Spillway [PDF]

E3S Web of Conferences, 2023
The Ogee Spillway is one of the most crucial flood control structures, and it is developed at the same time as dams. The Ogee Spillway's downstream portions experience scouring due to flow, a problem that persists in reality.

Numerical Modeling of 3D Flow Field among a Compound Stilling Basin

Mathematical Problems in Engineering, Volume 2019, Issue 1, 2019., 2019
Due to great velocity gradients among the outgoing flow, it is much common to form large‐scale reverse flow with oblique movements outside the conventional separated stilling basin. Aimed at above problems, this paper proposes to remove the longitudinal splitter wall and then physically and numerically investigate the corresponding influence upon the ...

Numerical Prediction and Risk Analysis of Hydraulic Cavitation Damage in a High‐Speed‐Flow Spillway

Shock and Vibration, Volume 2018, Issue 1, 2018., 2018
Hydraulic cavitation is usually an undesirable phenomenon since it can damage the concrete surface of a chute spillway. In order to numerically predict the potential cavitation of a high‐speed flow in a chute spillway, a compound risk assessment is proposed by combining probabilistic analysis with a computational fluid dynamics (CFD) technique.

Non‐Gaussian Hybrid Transfer Functions: Memorizing Mine Survivability Calculations

Mathematical Problems in Engineering, Volume 2015, Issue 1, 2015., 2015
Hybrid algorithms and models have received significant interest in recent years and are increasingly used to solve real‐world problems. Different from existing methods in radial basis transfer function construction, this study proposes a novel nonlinear‐weight hybrid algorithm involving the non‐Gaussian type radial basis transfer functions.

Weighed Nonlinear Hybrid Neural Networks in Underground Rescue Mission

International Scholarly Research Notices, Volume 2014, Issue 1, 2014., 2014
In our previous work, a novel model called compact radial basis function (CRBF) in a routing topology control has been modelled. The computational burden of Zhang and Gaussian transfer functions was modified by removing the power parameters on the models. The results showed outstanding performance over the Zhang and Gaussian models.

A Study of pressure fluctuation caused by hydraulic jump in stilling basin [PDF]

مهندسی منابع آب, 2018
A stilling basin is one of the energy dissipaters downstream of a spillway. The place of maximum pressure caused by jet impact and the effect of various factors on the amount and location of pressure are important factors in designing of stilling basin ...
