摘要:Within China's Loess Plateau there have been concerted revegetation efforts and engineering measures since the 1950s aimed at reducing soil erosion and land degradation. As a result, annual streamflow, sediment yield, and sediment concentration have all decreased considerabl...

摘要:During winters, the high-speed train travels in the northern of China is struck by to the snow, ice and coldness, massive snow accumulating on the bogies. To understand the cause of snow packing on the high-speed train’s bogies clearly, the 3-D unsteady Reynolds-averaged Nav...

摘要:Stemflow transports nutrient-enriched precipitation to the rhizosphere andfunctions as an efficient terrestrial flux in water-stressed ecosystems.However, its ecological significance has generally been underestimatedbecause it is relatively limited in amount, and the biotic ...

摘要:The prediction of flow around a high-speed train subjected to different windbreak walls and yaw angles has been investigated using steady Shear Stress Transport (SST) k-ω turbulence model at the Reynolds number of 1.0×106 based on the height of the scaled train model. The re...

摘要:In this paper, the aerodynamic performance of the head car of a CRH2 train running in sandstorms was investigated. A numerical simulation method based on Realizable k-ε turbulence model was used to explore the flow features around the high-speed train. The accuracy of mesh r...

摘要:A Detached Eddy Simulation (DES) method based on the SST k-ω turbulence model was used to investigate the instantaneous and time-averaged flow characteristics around the train with a slender body and high Reynolds number subjected to strong crosswinds. The evolution trends o...
