Shape Oscillation of a Single Microbubble in an Ultrasound Field

Figure 3

Shape oscillation of a microbubble at different oscillation modes, when f = 130 kHz and P_d = 42 kPa. The corresponding initial radii are 22 μm, 30 μm, 36 μm, 42 μm, 50 μm, and 56 μm. (a) n = 3; (b) n = 4; (c) n = 5; (d) n = 6; (e) n = 7; (f) n = 8.
