Abstract | The interaction of two bubbles is studied under the action of buoyancy and radiation modified Bjerknes forces in viscous compressible fluid. Viscous drag force for an unsteady creeping flow is also accounted; it includes both the quasi-stationary Stokes and history drag forces. The bubbles are assumed having equal radii, which oscillate harmonically in time, and they are considered to be floating side-by-side during the course of motion. Such oscillation of bubble radii results, in general, in the modified Bjerknes force exerting on the bubbles. In the limit of infinite wavelength of sound waves generated by oscillating bubbles, the Bjerknes force reduces to its traditional quasi-static form. Governing equations for the interaction of two bubbles are studied analytically and numerically. Results obtained have revealed complex behaviour of two bubbles which in almost equal initial conditions, either can coalesce or draw together up to some distances but then, move away from each other. |
