Web14 Apr 2024 · The continuous phase cannot squeeze the neck of droplet 2 due to the incompressibility of the solid core, so F p ≈ 0 and the estimated values of shear force and interfacial tension are F τ ≈ 0.327 μN and F γ ≈ 2.884 μN. The interfacial tension is significantly larger than the shear force, so droplet 2 does not break up.
