In this article, polyethylene oxide glycerin aqueous solution is used as the dispersed phase, and cyclohexane is used as the continuous phase to study the formation mechanism of viscoelastic fluid droplets in a step‐emulsification microdevice. The formation process of viscoelastic droplets mainly includes three stages: two‐dimensional expansion stage, necking stage, and pinch‐off stage. The elasticity...
In this paper, the formation mechanism of droplets of shear‐thinning non‐Newtonian fluids in a step‐emulsification microdevice is studied experimentally, by using aqueous solutions of sodium carboxymethyl cellulose (CMC) as the dispersed phase and cyclohexane as the continuous phase. According to the evolution of the front‐end length of the dispersed thread over time, the droplet generation process...
