| Abstract: | The control equations for the oscillation of the cloud of bubbles in a dilute solid liquid two phase flow have been worked out, and the analytical result of the sound pressure radiated from a cloud of bubbles oscillating in dilute solid liquid two phase flow are derived with the perturbation theory and the acoustic method. The influences of the number and size of the bubbles of the gas content in the mixture and of the solid particles on the oscillation of the cloud of bubbles are analyzed. |
