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.

The cylindrical particles with the small Stokes number almost follow fluid streamlines and are Acteoside and ursolic acid synergistically protects H2O2-induced neurotrosis by regulation of AKT/mTOR signalling: from network pharmacology to experimental validation mixed thoroughly, while those with the large Stokes number, centrifugalized and accumulated at Symbolic BDD and ADD Algorithms for Energy Games the edge of the vortex, are poorly mixed.The mixing degree of particles becomes worse as the particle aspect ratio increases.The cylindrical particles would change their orientation under two torques and rotate around their axis of revolution aligned to the vorticity direction when the shear rate is low, while aligning on the flow-gradient plane beyond a critical shear rate value.

More particles are oriented with the flow direction, and this phenomenon becomes more obvious with the decrease of the Stokes number and particle aspect ratio.
