Fig. 1. Water flow regimes.

Water flowing down a cotton thread with a diameter of 0.76 mm at flow rates of (A) ${\stackrel{.}{\mathit{m}}}_{\text{Lps}}$ = 0.015 to 0.06 g/s, resulting in the Rayleigh-Plateau instability regime, where beads have constant velocities and spacings, and (B) ${\stackrel{.}{\mathit{m}}}_{\text{Lps}}$ = 0.11 g/s, generating a flow in the convective instability regime that features bead coalescence (Nozzle inner diameter = 0.8 mm).
