Flow instability of colloidal dispersions flowing through a very small orifice

Flow property through a very small orifice has been measured for dilute aqueous colloids including fine particles about 120 nm in diameter. In the experiment, fine Polystyrene particles dispersed in water with 1% volume fraction are investigated and in this volume fraction an electrostatic repulsion...

description Flow property through a very small orifice has been measured for dilute aqueous colloids including fine particles about 120 nm in diameter. In the experiment, fine Polystyrene particles dispersed in water with 1% volume fraction are investigated and in this volume fraction an electrostatic repulsion and a van der Waals attraction among the particles play a significant role in the flow. On the pressure drops flow through a small orifice, the particle surface interactions have little influence. But, these effect dominantly the flow instabilities. The particles having strong repulsion increase flow instability, and these having strong attraction suppress the flow instability. Criterion whether the orifice flow is stable or not is predicted by comparison of the second minimum location of the surface potential and the mean surfaces distance of the particles.
