Analytical Modeling for Dispersion of Passive Analyte in Microfluidic Device
Project Advisor
Prof Lam Yee Cheong
Duration :
July 2003 to October 2004

Project Abstract:

The research focuses on the understanding and the development of theoretical and numerical model to described dispersion of passive solute in microfluidic device for Newtonian fluid under pressure driven flow. The results will have a direct application to analytical and bioanalytical chemistry. Analytical modeling will be employed to consider the axial dispersion of a solute along the flow direction, to simulate convection and diffusion transport in a pressure driven creeping flow for a rectangular shape slit. This represents the first effort in applying the lubrication approximation and averaging methods to the analysis of analyte concentration in microfluidic slit device, taking consideration of Taylor’s dispersion. It now opens the door for optimization for such devices. Future plan is to extend the model for non-Newtonian flow, electrokinetic driven flow, and combination of pressure driven and electrokinetic driven flow.

Numerical Simulation of Electroosmotic Flow
Project Advisor
Prof Lam Yee Cheong
Duration :
July 2004 to December 2004

Project Abstract:

Electroosmostic flow is a convenient mechanism for transporting polar fluid in microfluidic device. It has many applications to analytical and bio-analytical chemistry as it has a uniform flow velocity profile and no moving parts. The research focuses on the development of numerical model for electroosmotic flow which is governed by the modified Navier-Stoke equation governing the velocity field and a non-linear two-dimensional Poisson-Boltzman equation governing the electrical double-layer (EDL) field distribution and the coupled governing equations are solved numerically by using finite control-volume method.
