Discussion Overview

The discussion revolves around shock wave boundary layer interactions (SWBLI) occurring at supersonic speeds, particularly in the context of moving ramps or oscillating flaps. Participants seek to understand the phenomena and the lack of comprehensive literature on the subject, including educational resources suitable for beginners.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant notes the absence of solid literature on SWBLI despite its mention in research papers, indicating a need for better understanding of the phenomena.
  • Another participant suggests a specific paper by J.-P. Dussauge as a potential resource, while acknowledging that it does not provide a complete explanation.
  • A participant expresses interest in finding a college-level book that covers the topic comprehensively for beginners, indicating a gap in accessible educational materials.
  • One participant emphasizes that the question of what occurs in the shock wave region remains open and unpredictable, highlighting ongoing research efforts to analyze the reasons for unsteadiness in this context.
  • Participants engage in casual conversation about their locations and affiliations, revealing they are both in India and possibly working on related projects.

Areas of Agreement / Disagreement

Participants generally agree on the lack of comprehensive resources and the open nature of the questions surrounding SWBLI. Multiple competing views on the availability of literature and understanding of the phenomena remain unresolved.

Contextual Notes

Limitations include the absence of definitive descriptions in existing literature, the unpredictability of downstream conditions, and the reliance on published papers for further insights.

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 anyone help me in this direction?
Something to better understand what exactly happens around that region?
TIA
 
Physics news on Phys.org
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 don't 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. :)
 
ok cool ... yea i guess i'll probably be doing that this summer :)
well by the way, where is your place exactly?

INDIA :)
good, you'll enjoy the thing!
by the way, where are you from?
 
india bro are you working on some DRDO sponsored project.?
 
yeah!
where in INDIA are u?
 
shucks...
dude i sit ryt nxt 2 u in brijesh's lab!
ritesh
Wth!
