Chris, yes, it seems to be all about bumps and indentations on wings...

11:11 Oct 12, 2009 

It rather depends what they're on about. If this is a discussion of fluid dynamics over a lifting surface, eg a wing, then "soufflage" and "aspiration" could be referring to blowing or sucking air over or from slots or perforations in the wing (both established methods of lift and/or drag control).

thanks for your efforts.... I may just ask that the customer be asked! shock horror!

10:46 Oct 12, 2009 

soufflage ou aspiration would seem to suggest so. Possibly relèvement could refer to raising of water, as in station de relèvement, though I cannot say I can fit this interpretation into the sentence!

09:41 Oct 12, 2009 

oh right, relèvement, lifting something up..... as I say, they're rattling off ideas, I'll have another look from that angle.. funny way to express it 'tho.... thanks

Bourth, hello... hmmm, could be, could be.....
Here is a fragment of the text (equations and stuff zzzzzz ed out)... it is in a section where they're firing off ideas about future research... in the main body of the paper its a LOT of mathematical models but SOME experimental verification, observation and stuff.

"A l'aide d'un relèvement, on peut traiter aussi le cas d'un contrôle pariétal du champ de base : xxxxxxxxxxx. Ici yyyyyyyyy désigne la modification des conditions de Dirichlet à la paroi
qui s'impose au champ de base zzzzzzzz.
Dans ce cas la sensibilité aaaaaaaa de la valeur singulière par rapport à la modification du champ de vitesse à la paroi (soufflage ou aspiration stationnaire) est définie selon :...... blah blah"

does that help?!

Have they got a physical model in a wind tunnel/water? Even if not, but purely mathematical models, might it be that they raise the model or change it's angle of incidence? This could facilitate calculation of surface flow conditions maybe? Does "pariétal" refer to an object in the air/water flow or to the walls/boundaries of the simulation, etc. etc.?

07:57 Oct 12, 2009 

could it be "bearing" after all? they go on to speak about Dirichlet conditions

07:52 Oct 12, 2009 

pressure measurements? mostly they're talking about eigenvalues! yes, "reading", but I think that is a bit too light ! the text is quite theoretical (although they do mention experiments) so even plot doesn't convince me too much.

07:26 Oct 12, 2009 

More generally, a relèvement is just a "reading", eg off a graph or instrument. "Plot" may be too specific. Parietal is an odd use, referring usually to biological "walls", but if the context is fluid mechanics, could be referring to boundary effects (which are very important). Are they talking about pressure measurements?

07:22 Oct 12, 2009 

I think I'm going to keep it as "light" as possible.... don't want to betray my ignorance
have a good day, I'll send you some points for these questions if I don't get anything else

06:58 Oct 12, 2009 

but plot seems good, or maybe 'by plotting bearings', or 'by plotting points'? My dictionary gives 'magnetic/compass bearing' as the translation for 'relèvement'...
