【 摘 要 】

A numerical model for the particles levitation in an ultrasonic field is developed on the basis of the finite difference time domain method. The force effect of the ultrasonic field on the particles is calculated via gradient of the Gor'kov potential, also the friction force in gases for spherical particles is taken into account. With the help of the OpenCL technology, a parallel computation of the trajectories of a set of particles is implemented.
