Numerical Simulations of the Impact and Spreading of a Particulate Drop on a Solid Substrate by Hyun Jun Jeong, Wook Ryol Hwang, Chongyoup Kim

“…The Navier-Stokes equation is solved by a finite-element-based computational scheme that employs the level-set method for the accurate interface description between the drop fluid and air and a fictitious domain method for suspended particles to account for full hydrodynamic interaction. Focusing on the particle effect on droplet spreading and recoil behaviors, we report that suspended particles suppress the droplet oscillation and deformation, by investigating the drop deformations for various Reynolds numbers. …”

Numerical Simulation Study on Influence of Riverbed Changes on Saltwater Intrusion in Northwest River Delta by JIN Gaoyang, ZHU Sanhua, CAO Yihao

“…To study the changes in the riverbed of the Northwest River Delta and their relationship with saltwater intrusion,this paper builds a one-dimensional unsteady flow chlorine concentration mathematical model based on the collection and organization of previous research results,hydrological,meteorological,and river terrain data.The hydrodynamic and chlorine concentration verification results meet the relevant regulatory requirements and can be applied to calculate and analyze the impact of riverbed changes on saltwater intrusion.The research results are as follows.① From 1999 to 2016, the riverbed of the Northwest River Delta network was in an uneven downward cutting state,and the volume of the river continued to increase,resulting in a decrease in the resistance of the estuary to rising and falling tides.The upward tracing of high saltwater masses along the estuary was simpler,and the upward tracing of salt tides became increasingly severe.② The rising tide at each Koumen station increases,and the probability of removing freshwater from the saltwater boundary decreases.Under different inflow conditions in Sixianjiao,the average upward movement of the saltwater boundary at Modaomen Waterway is 3 735 m,and the average downward movement of the freshwater from Pinggang Pumping Station is 5.33%.The average upward movement of the saltwater boundary at Shawan Waterway is 2 369 m,and the average downward movement of the freshwater from Shawan No.1 Water Plant is 5.14%.These seriously affect the ecosystem and normal water intake demand in the estuarine area.The research results can provide basic support for the research and engineering design of water supply safety measures in the Northwest River Delta and estuarine areas.…”

Risk Analysis of Sequential Dam Break of Cascade Reservoirs and Simulation of Flood Routing by YU Zibo, XIANG Yan, MENG Ying, SU Zhengyang

“…To study the risk of sequential dam break of cascade reservoirs,and to simulate and analyze the flood routing process,by constructing a Bayesian network model for the sequential dam break of double reservoirs under the action of extra standard floods and piping,and combining the dam break and flood routing simulation of Breach dam-break numerical model and two-dimensional HEC-RAS hydrodynamic model,this paper calculates the probability of dam break,evaluates the risk of sequential dam break,and simulates the flood routing process,taking Hanconggou Reservoir and Dingguoshan Reservoir as examples.The calculation results show that:Through Bayesian-based backward inference of the known dam break of Dingguoshan Reservoir,the probability of “Hancongou Reservoir dam break” increased from 3% to 87%;while through Bayesian-based backward inference of the known dam break of Hancongou Reservoir,the probability of “Hancongou Reservoir piping” increased from 16% to 87%.Under extra standard flood and piping conditions,due to the sequential dam break of the two reservoirs,the time for the flood to reach the section CS1—CS6 is 0.8~3.0 h;under the flood conditions that occurred once in 1 000 years,the Hancongou Reservoir was opened for flood discharge but the dam was not broken.Only the Dingguoshan Reservoir was over-topped with dam break,and the flood reached the section CS1—CS6 in 21.5~26.5 h.This study can provide scientific reference for reducing dam break risk,and making emergency plan and disaster prevention & mitigation plan.…”
