A Computational Model with Experimental Validation for DNA Flow in Microchannels

Nonaka A., Gulati S., Trebotich D., Miller G.H., Muller S., Liepmann D., UC Davis / Lawrence Livermore National Laboratory, US

We compare a computational model to experimental data for DNA-laden flow in microchannels. The purpose of this work in progress is to validate a new numerical algorithm for viscoelastic flow of an Oldroyd-B fluid. Significant [...]

A Numerical Algorithm for Complex Biological Flow in Irregular Microdevice Geometries

Trebotich D., Colella P., Miller G.H., Nonaka A., Marshall T., Gulati S., Liepmann D., Lawrence Livermore National Laboratory, US

We present a numerical algorithm to simulate non-Newtonian flow in complex microdevice components. The model consists of continuum viscoelastic incompressible flow in irregular microscale geometries. Our numerical approach is the projection method of Bell, Colella [...]
