Q

What is the difference between convective and disperse mixing?

A

Disperse mixing involves breaking down materials into smaller particles or droplets and distributing them evenly within a medium. It is driven by mechanical forces

Convective mixing occurs when large-scale fluid motions or currents drive the movement of materials within a medium.
