A Robust Approach for Estimating Diffusion Constants from Concentration Data in Microchannel Mixers

Coelho C.P., Desai S., Freeman D., White J.K., Massachusetts Institute of Technology, US

In this paper we present a robust and geometry independent method for the estimation of diffusion coeffients of solutes from image data. Our diffusion coefficient estimation algorithm works in two steps. First, given the device [...]

Numerical Simulation of Microfluidic Flow Using a Combination of Micro and Macro Computational Techniques: Scaling Issues

Mautner T., SPAWAR Systems Center San Diego, US

Recent literature has demonstrated the possibilities of using configurable surfaces to enhance the flow of fluids in MEMS devices. Not only are surface properties important in fluid delivery, the inherent problems of mixing by diffusion [...]
