From: Coalescence of two growing bubbles in a Hele–Shaw cell
(a) Definition of bubble distortion (2021053104). (b–d) Bubble distortion just before coalescence \(Dis(t_c)\) as functions of (b) decompression rate \(\left| dp/dt \right|\), (c) viscosity, and (d) cell gap. Marker color indicates the initial film thickness. (b) \(\eta =1 \ \mathrm{Pa \cdot s}\) and \(D=0.3 \ \mathrm{mm}\). (c) \(dp/dt=-0.3 \ \mathrm{kPa/s}\). \(D=0.3\) or \(1.0 \ \mathrm{mm}\). (d) \(\eta =10 \ \mathrm{Pa \cdot s}\). \(dp/dt=-1.5\) or \(-0.3 \ \mathrm{kPa/s}\).
