Figure 10

Ensemble-averaged pulsatile bubble propagation streamlines in the bubble tip frame of reference at the points in the oscillatory cycle (a–d) depicted in figures 8 and 9. The time-dependent downstream centerline velocity U(t) = UM + UΩ sin(ωt) where the time-averaged downstream centerline velocity UM = 12 mm s−1, the frequency ω = 1 Hz and the oscillatory velocity component UΩ = 6 mm s−1 (CaM = 8.1 × 10−5).
