Numerical simulation of junction point pressure during droplet formation in a microfluidic T-junction

▸ Simulation for droplet formation with two phase flow level set method in 3D. ▸ Five kinds of flow patterns of the droplet formation process are investigated. ▸ The pressure of the junction point during the droplet formation process can reflect the flow pattern directly. ▸ The influence of static contact angle of dispersed phase flow is essential in the droplet formation process.
