Microwell Jet Mixing Nick Cox
This project involved the determination of the mixing time for the jet injection and removal of a concentrated fluid in a small microwell. Experimental conditions were modeled using Comsol Multiphysics©. The figure above shows the concentration distribution after some injection. The top surface has risen due to the added mass. The variance in concentration was plotted as a function of time, and the mixing time was approximated graphically as the point where the concentration variance returned to near-initial values. Results indicate a mixing time of approximately 2.35 seconds.
