Abstracts of Talks

James Friend Center for Medical Devices University of California — San Diego Acoustic Streaming The analysis and use of acoustic streaming has taken on new urgency in the past few years with the recognition that classical analysis methods are unable to accurately quantify the flows generated by passing acoustic waves beyond a few hundred kHz. This issue, known since at least Lighthill’s namesake publication in the 1970s, has not been addressed in the time since, with many researchers—including the author—resorting to computational analysis and approximations to overcome at least some of the problems. Moreover, few researchers have been willing to consider the dynamic behavior of acoustic streaming: the delayed onset, the response to inharmonic excitation, and the delayed flows after the acoustic wave ceases, though these aspects are important in many experiments. Much of the reason is the challenge of the analysis of such flows. After considerable work via an alternative analysis path, we may finally have arrived at a method for closed-form analysis of acoustic streaming at least in one dimension, with transient behavior and both nonlinear compressibility and viscous effects included. We present a coherent and straightforward plan for analyzing simple acoustic streaming cases where classic theories fall short.
