Description
Lijun Yang and five co-authors tune a tiny chip mixer that blends fluids with no moving parts. Such micromixers mix by shape alone, and shape changes are the main way to boost them. Their 2026 design adds variable section units whose cross shape changes along the path. Four knobs are in play: the unit type, where the units start, how many there are, and their size ratio.
Flow simulations ran the knobs through their ranges. One channel type won, with units set at the start, four in number, and a size ratio of one to four. With that setup, the mixing index passed 0.96 at a Reynolds number of 100. Poor shapes fell far short of that mark. The team offers the result as a plain recipe for chip mixers that blend well. Bench builds would be the next proof.
