Gas absorption into a drop in the presence of an acoustic field

The results indicate that the effect of the acoustic field on mass transfer is especially beneficial for absorption processes without chemical reaction, or with reactions of moderate rates. The enhancement for these processes for Peclet numbers of 500-1000 was 3.3-3.5 as compared to absorption without an acoustic field. For processes with fast chemical reactions the benefits of using an acoustic field are limited, with enhancement factors in the range of 1.5-2.3.
