Aerospace Shockwave-Boundary layer interaction

  1. May 19, 2009 #1
    Hi
    In the case of a moving ramp/oscillating flap at supersonic speeds(m=2.8-3), we get a shock wave boundary layer interaction which is although mentioned in most research papers but no solid literary piece is found on it.( as i checked out)
    Can any one help me in this direction?
    Something to better understand what exactly happens around that region?
    TIA

    i wonder if u checked this:
    Shock/boundary-layer interactions: Possible sources of unsteadiness- J.-P. Dussauge

    its available at Science Direct. It gives a good insight into the problem. A full-filling explanation is still not there, though. :(

    u can refer to other papers by Dassauge & Dolling too.
    hope this helps a bit.

    thanks for your reply
    i have read into the papers by Dolling and further by Chapman et al.
    But what i wanted to know was that , is there any college level book looking into this problem in general, so that it might help a beginner too to understand this.
    TIA

    as i told you, the question is still very much open... you won't find a good description in any book. :(
    All we know is 'something happens around that place', what is it, we dont know, neither can we predict the downstraeam conditions accurately.
    At my place, we're trying to analyse reason for this unsteadiness. In case i get something solid, i'd let you know. for the time being, all we can do is keep looking into the published papers.
    have a good time studying SWBLI. :)
