Microfluidic mixer study

Placeholder case study — to be replaced with the real write-up.

Overview

A study comparing passive micromixer geometries to find the best trade-off between mixing efficiency and pressure drop for a low-Reynolds-number flow.

Approach

• Built a parametric CFD model and swept channel width, serpentine pitch, and flow rate.
• Quantified mixing with a concentration-uniformity index sampled at the outlet.
• Tracked pressure drop alongside, so efficiency was never read in isolation.

Results

The serpentine geometry reached target uniformity at roughly half the channel length of the straight baseline, for a modest pressure-drop penalty.

What I’d do next

Prototype the top candidate and validate the simulated mixing against dye experiments.
