No full textThis work describes results of theoretical study of bubble dynamics in an acoustic field. It is known that there is a radiation force on a bubble in an acoustic resonator. This force can provide conditions of bubble levitation. We consider forces acting on a bubble in a resonator with flowing liquid. It is described in the paper bubble motion in such a condition for different parameters. Results of calculations are discussed
