Schematic of the simulation setup for the wave-cloud interaction problem. We excite a planer, 10 cycles of a sinusoidal pressure wave with an amplitude of 1.0 MPa and a frequency of 300 kHz from a source plane located at x = −20 mm in the +x direction. A bubble cloud with a radius of 2.5 mm is located at the origin. 625 Bubbles are randomly distributed in the region of the cloud. The radii of bubbles follow Gaussian distribution with a mean of 10 μm and a standard deviation of 2.5 μm. The initial void fraction of the cloud is β0 = 4.87 × 10−5.
