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.
