Optimal clearances (0.05–0.08 mm) are derived from Navier–Stokes simulations, balancing capillary hold‑back against gravity‑driven flow.
Transient Flow Analysis:

Transient CFD captures how viscous serums (1,000–5,000 cP) accelerate into the neck channel, preventing air entrapment and ensuring a drip‑free start.
