Micro Total Analysis Systems (μTAS) require rapid yet homogeneous mixing of a number of fluid streams that carry bio/chemical species in the solution. Current analysis has been continued from our previously published work . New models were designed by rendering some particular fluid and geometric variables from the original design and then analyzed for the degree of mixing effectiveness. A careful placement of obstacles in the mixing zone of the model and the electrodes in it showed enhancement in mixing performance. In addition, models with varied geometrical parameters such as converging inlet and diverging outlet yielded even better mixing capabilities. Concentration variances over time at the outlet were simultaneously compared in all models for mixing. Also average concentration was tracked over time so as to confirm the uniformity in mixing. The concentration variances at the outlet have been dramatically observed to be reduced by a factor of at least 10 from our designs as reported earlier .
