An absorption enhancement technique and testing results are presented here. The technique increases the mixing rates at the solution-vapor interface. The second qualifying quality is that, unlike additives, this technique may not require periodic replenishment of organic compounds depleted by thermal instability effects. The results shown here cover a range of solution Reynolds numbers from 20 to 300, with mixing scales from 0.2 to I mm, and mixing frequencies from 20 to 100 Hz for solution flow over a vertical flat plate. Analysis shows that significant increases of the absorption rate are possible.
