Vibroresonance conditions of motion of gas-liquid media in the structures under polyharmonic excitation

摘要

Results of experimental investigations of dynamic behaviour of gas-liquid media under two-frequency vibration excitation in the cylindrical, spherical and ellipsoidal shells. Failure specificity of free surface of liquid, formation of gas bubbles and their local groups have been revealed. Basic formation regularities and dynamic stability of nonlinear vibration system liquid-gas have been Investigated. Intensification of the processes of vibromixing of gas-liquid media under two-frequency excitation as compared to one-frequency excitation.
