Figure 13:

Effects of the viscosity μ (at fixed $T_{in}^{P+}$) on periodicity in the outlet channel showing the baseline (μ = 0.59 g cm⁻¹ sec⁻¹, ΔP =32547 dyn cm⁻²) and high viscosity (μ = 0.059 g/cm sec, ΔP = 38800 dyn cm⁻²) cases where γ = 3.6 dyn cm⁻¹, R = 50 μm, and α = 0.9. At a given T_in, periodicity is greater for the high-viscosity case because the Poiseuille pressure drop has increased while the droplet pressure drop remains relatively constant. Large symbols indicate transition region points.
