Brian Rast Od
Perla Bermudez, OD. Bermudez is a Therapeutic Optometrist and Optometric Glaucoma Specialist. She specializes in a series of tests to assess acuity, refraction, and potential eye diseases. For good practical reasons, most experimental observations of turbulent flow are made at fixed points x in space at time t and most numerical calculations are performed on a fixed spatial grid and at fixed times. On the other hand, it is possible to describe the flow in terms of the velocity and concentration (and other quantities of interest) at a point moving with the flow.
