From rotating impellers stirring air into a liquid, to a turbulent jet entering a moving flow, mixing processes are essential to almost every industrial application you can think of. Omar Matar and his research group at Imperial College London are experts in running numerical simulations to model mixing in multiphase flows. Here, we see examples of mixing in stirred tanks, mixing through droplet collisions, and mixing at interfaces.
