Abstract

The present work aims to model fully developed laminar flow, particularly pulsed flow, of Newtonian fluids in rectangular channels and to analyze the application of pulsed flow to microfluidic devices. For this purpose simulation using GAMBIT version 2.2 and FLUENT version 6.2 are extended. The meshes generated had been tested for grid independency and the result numerically iterated by FLUENT have to validate from published paper. Simulation solutions for these flow properties under any pressure gradient are obtained and simplified for periodic pressure gradients. The pulsating flow amplitude was 50% of the mean pressure and the flow regime is laminar. Pulsation tested with frequency by 5 kHz and the result of simulation had been analyzed and compared to various published data. The validation was unsuccessful due to difficulty to get a complete data from published analytical paper and too many assumptions had to be made, resulting to unsuccessful validation. Although, the validation of the model was unsuccessful, this study has somehow show a possibility of simulating oscillating flow using Computational Fluid Dynamic software (CFD).
