The motion of cylindrical particles in a mixing layer is studied using the pseudospectral method and discrete particle model. The effect of the Stokes number and particle aspect ratio on the mixing and orientation distribution of cylindrical particles is analyzed. The results show that the rollup of mixing layer drives the particles to the edge of the vortex by centrifugal force. https://www.getpureroutine.com/hot-sale-ethical-nutrients-mega-magnesium-powder-citrus-450g-for-sale-save-big/
