Controlled Diffusion Micromixer

Application ID: 12641

This model simulates an H-shaped micro-cell designed for controlled diffusive mixing. The cell puts two different laminar streams in contact for a controlled period of time. The contact surface is well-defined and, by controlling the flow rate, it is possible to control the amount of species that are transported from one stream to the other through diffusion. This example was originally formulated by Albert Witarsa under Professor Bruce Finlayson's supervision at the University of Washington in Seattle. The work was done as part of a graduate course assignment to evaluate the potential of patents in microfluidics through mathematical modeling.

This model example illustrates applications of this type that would nominally be built using the following products:
