The effect of Reynolds number and Stokes number on particle motion and separation is discussed by analyzing the hydrodynamic behaviors of aerosol particles in reverse flow cyclones.

By data processing of many images obtained in the experiments, it is found that the particles at the Stokes number of 0.

Finally,the parameter of particle size was also investigated,and the particles with a smaller Stokes number had weaker influence on the flow field.

Study on transport and diffusion of contaminants in nonlinear Stokes waves;

Numerical generation of Stokes waves;

Combined with the nonlinear Stokes wave and the parallel flow instability theory,the high-order inviscid Orr-Sommerfeld equations,the formulas of pressure over wave surface and the energy transfer are derived.

The result shows that the Stokes beam generated propagates in the LP01 mode,and the process of incoherent beam combing is an inverse process that the mixed beams are decomposed into the linearly polarized beam.

A new analytical method of symplectic system,Hamiltonian system,was introduced for solving the problem of the Stokes flow in two-dimensional rectangular domain.

In this paper,the problem of two dimensional Stokes flow is reduced to the determination of eigenvalues and eigensolutions in a Hamiltonian system.

Stokes flow is the main and typical flow model of viscous fluid.
