【摘 要】

：

针对低浓度含金溶液,研究了以旋流电积法一步电积金,考察了溶液浓度、电流密度、溶液pH等条件对Au3+电积析出的影响.结果表明:对于2 L碱性电解液,在金质量浓度5 mg/L、电流密度20 A/m2、电积时间2.0 h条件下,电积效果较好,金析出率达94.66％,溶液中Au3+质量浓度可降至0.267 mg/L,耗电量为6.72 kW·h.旋流电积法可用于从低浓度溶液中回收金.

Velocity and turbulence characteristics in an open channel with multi-row staggered vegetation patch

A staggered distribution of vegetation is very common in nature,which might significantly affect the flow structure.To investigate its impact,three rows of staggered vegetation groups are designed under seven different working conditions.The horizontal an

A high precision computing method for heat transfer in the process of oil-water displacement

The process of oil-water displacement is one of the key technologies in offshore underwater tank.When hot oil is contacting the normal-temperature water,the interracial heat transfer should be investigated as the heat loss may result in wax precipitation

A simple analytical model to predict liquid unloading in the horizontal gas well

An accurate prediction of the critical gas velocity for the liquid loading is of great importance for operators to select the tubing diameter for the newly drilled gas wells,or to optimize the production rate for production wells.It is clear from previous

Heat transfer and plume statistics in turbulent thermal convection with sparse fractal roughness

Rough-surface Rayleigh-Bénard convection is investigated using direct numerical simulations in two-dimensional convection cells with aspect ratio Γ=2.Three types of fractal roughness elements,which are marked as nl,n2 and n3,are constructed based on the K

Transient simulation and analysis of the simultaneous load rejection process in pumped storage power

The load rejection imposes a danger in the pumped storage hydropower plants (PSPs),especially when two or more pump turbines reject their loads simultaneously.In this paper,the simultaneous load rejection scenarios in the PSPs are simulated and analyzed b
