To suppress the adverse effect of the gear windage phenomenon in the high-speed aeronautic industry. a shroud as an effective alternative strategy is usually to enclose gears to reduce the windage behaviors of high-speed gears. To deeply understand these no-load power losses. this paper proposes a new simulation methodology based on the Lattice Boltzmann method to study the windage lo... https://unitedssports.shop/product-category/bike-units-hardtail-recreation/
