Key Findings in This Report

• A theoretical model based on force balance accurately predicts the critical Capillary number for droplet breakup in T-junction microchannels. • Increasing sidearm length ratio inhibits droplet breakup and induces asymmetric breakup regimes. • Increasing outlet-to-inlet width ratio reduces the likelihood of droplet breakup. • The model provides a predictive framework for controlling droplet dynamics in lab-on-a-chip applications.
