Performance Assessment of Shockwaves of Chute Spillways in Large Dams
Shock and Vibration, Volume 2021, Issue 1, 2021., 2021 Spillways are the most important structures of large dams that are responsible for releasing the excessive flood discharge from the reservoir. Although many studies have been performed to determine the flow characteristics over these structures, however, the available information on the shockwaves’ characteristics for spillways’ design is limited.

Geofluids, Volume 2021, Issue 1, 2021., 2021 The high rock slope situated in the Southwest stope of Taiping Mining, Inner Mongolia, is subject to dumping failure due to its instability. The dumping body rock layer of this stope shows obvious bending and lowering of the head. The overturning angle of the rock strata can reach 46°, and tension dislocation along the rock joint can be observed in ...

The Depositional Record, Volume 6, Issue 1, Page 203-216, February 2020., 2020 An increasing number of studies uses simplified modelling of turbidity currents to reconstruct historic and ancient sediment fluxes to the deep sea. The commonly used Rouse model is validated here with experimental data. The results indicate that the Rouse model is accurate for the distribution and throughput of sand along the channel thalweg, but ...

SPH simulation of free overfall in open channels with even and uneven bottom [PDF]
, 2013 The free overfall can be used as a simple and accurate device for flow measurement in open channels. In the past, the solution to this problem was found mainly through simplified theoretical expressions or on the basis of experimental data. In this paper,

Variation of Water Depth on Normal and Skewed Broad Crested Weirs
Tikrit Journal of Engineering Sciences, 2007 This paper present the variation between brink and critical depths for free overfall, of water over two models of broad crested weirs with different edge, straight vertical and skewed with an angle (30)o. The discharge was measured for the two models and

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 ...

Mathematical Problems in Engineering, Volume 2013, Issue 1, 2013., 2013 Adjusting and controlling the relative humidity (RH) inside package is crucial for ensuring the quality of modified atmosphere packaging (MAP) of fresh produce. In this paper, an improved kinetic model for predicting the RH in MAP was developed. The model was based on heat exchange and gases mass transport phenomena across the package, gases heat ...
