Summary: Environmental fluid dynamics is the study of natural motions on the earth surface akin to river dynamics, oceanic circulation, weather, atmospheric circulation and climate. Almost all the flows concerned by environmental fluid dynamics are turbulence, and turbulence usually controls important processes in environmental fluids such as erosion of the earth surface, mass and heat transfers, migration and mixing of pollutants. The special issue focuses on recent development and research studies in the area of the effects of turbulence on sediment transport, material transport, pollutant dispersion in rivers, oceans and atmospheres. The papers may present novel analytical, numerical or experimental findings within the context of turbulence and environmental fluids.
Interesting topics considered are including but not limited to the following:
1) Turbulence in open channel flows
2) Flow and sediment transport in rivers and lakes
3) Monsoon and ocean current
4) Gravity current in oceans and atmospheres
4) Pollutant transport and mixing in rivers, oceans and atmospheres
6) Numerical modeling of environmental fluids

    Abstract The interaction of U-shaped rings used for power transmission hardware with a wind-sand field is simulated numerically. A standard turbulence model is used in synergy with an Eulerian-Lagrangian approach. The results show that the wind pressure on the windward side of the U-shaped ring is the highest, a negative pressure zone appears on both sides of the U-shaped ring, while a Kármán Vortex Street is created on its leeward side. There are three possible regimes of motion for the sand grains in the wind field. Sand grains with size below 0.125 mm can follow the airflow directly into the contact… More >
