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 More >
