Pumped storage units are the main parts in China\'s power construction,as a hot issue concerned by the industry.The pump turbine involves the two-way flows and a multiple condition operation,and its operation flow pattern is very complex.The particle im
In this paper,a multiphase moving particle semi-implicit (MPS) method is developed by introduction of various multiphase models into the original MPS method for single-phase flows,and is then applied to the numerical simulations of two-layer-liquid and th
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
For the study of the effects of partially non-submerged rigid vegetation on the free-surface confluence flow in a curved open channel,a numerical simulation is carried out by using the Volume of Fluid model combined with the porous media model with the so
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
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
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
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
The air layer drag reduction (ALDR) of an axisymmetric body in oscillatory motions is investigated in this paper with open source toolbox OpenFOAM.The unsteady Reynolds-averaged Navier-Stokes (URANS) equations are used to determine the viscous flow and th
