Analysis on temporal and spatial variations of groundwater hydrochemical characteristics in the past decade in southern plain of Beijing, China
Beijing Groundwater Hydrochemical characteristics
2018/3/23
Groundwater utilization and protection are crucial for sustainable urban development. This is especially true for Beijing, where groundwater is an important source for urban water supply. In this stud...
• In 1960 the underlying principles of fluid dynamics and the formulation of the
governing equations (potential flow, Euler, RANS) were well established
• The new element wa...
Both third-order and fourth-order SD methods
are used on unstructured quadrilateral grids. The vortex shedding pattern of an airfoil
in an oscillating plunge motion becomes asymmetric at a su±cientl...
Culturomics meets random fractal theory: Insights into long-range correlations of social and natural phenomena over the past two centuries
Culturomics meets random fractal theory Insights long-range correlations social natural phenomena two centuries
2012/2/27
Culturomics was recently introduced as the application of high-throughput data collection and analysis to the study of human culture. Here we make use of this data by investigating fluctuations in yea...
Scale-adaptive simulation of flow past wavy cylinders at a subcritical Reynolds number
Wavy cylinders Drag reduction Vortex shedding Vibration control SAS
2012/2/29
The Xu {&} Yan scale-adaptive simulation (XY-SAS) model is employed to simulate the flows past wavy cylinders at Reynolds number 8\times 10^3 . This approach yields results in good agreement with expe...
Joule heating effects on a micropolar fluid past a stretching sheet with variable electric conductivity
joule heating magnetic field micropolar fluid stretching sheet
2010/3/11
The magneto-hydrodynamic (MHD) and joule heating effect on a laminar micropolar fluid boundary layer past a continuous, linearly stretching, non-isothermal sheet (with prescribed wall heat flux) is co...
Numerical simulation of flow past a cylinder in orbital motion
circular cylinder lock-in orbital motion vortex shedding unsteady flow
2010/3/12
A finite di®erence solution is presented for 2D laminar unsteady flow around a circular cylinder in orbital motion placed in a uniform flow for Re = 130, 160, and 180. Four cases displaying full l...
