Acoustic streaming

  1. Jan 30, 2008 #1
    Hello All,

    I have become interested in the study of nonlinear acoustic/longitudinal wave effects and came across this interesting article on HowStuffWorks.com which talks about Acoustic levitation:


    On the above link, they post the following, which I found very interesting:

    I am particularly interested in the third item, acoustic streaming. What I am wondering is if there is an electromagnetic analog to this phenomenon? Would it be possible to induce a DC current (closed ring) or a DC voltage potential (open loop) on a wire using a longitudinal wave directed along the length of said wire (through the space surrounding the wire, not through the wire itself). I have heard of similar effects taking place in plasmas but I'm not sure if that would apply in this case.

    Any thoughts or comments appreciated.
