Paper Abstract

In this study a stochastic model is applied in order to determine flow characteristics at the particulate level in a micro-channel. Model equations were discretized using Central Difference and Backward Difference methods and solved using the Jacobi method. The solution to the model equations provides the probability distribution of the distance traveled by a particle in the micro-channel as a function of time and reflects the dispersion property of the flow. From the probability distribution, residence time of a particle in the micro-channel is determined. Knowledge of Residence time and of dispersion characteristics is essential in studying the performance of a micro-reactor or in studies related to molecular or particulate flow in biological systems.
