HiClone air swirler
Tyke:
--- Quote --- Safari snorkel aperture has a cross-sectional area of 14x10cm

But only at some infinitely thin section . . . . the tube is tapered . . . . . and also not of true form, this complicates determining the losses at bends etc.
I would expect that the changes in section, direction and form would result in complex boundary effects and the resulting velocity profiles and pressures would be quite difficult to determine. Without 'proper' data and testing it would be very difficult to 'predict' what is actually happening inside the airbox and how the engine is actually using the air that is available to it.
For my money, by fitting a snorkel, any small losses or gains in performance are completly irrelevent when i'm over the bonnet dropping into a ford . . . . I'd sooner my engine breathed air rather than water.
Oh !!!! . . . . . Hi-Clones . . . that's where we were . . . . In theory they should work, but I'll go with go the majority of the guys . . . . 'till someone else proves different :wink:

Hi all :D
As I said if you prove me to be wrong with your theory I will gladly eat humble pie and apologise. :oops:
And because I do not pretend to be a qualified engineer and can only rely on information that I have acquired over the years from different publications and such like that perhaps I have miss read or was mislead. I am willing to admit or be it grudgingly that I may be wrong. :twisted: Please don’t forget I am a man (we are never wrong ask the wife) :twisted:
But take notice that the pest will admit when I am proved wrong. :wink:
what way Mr RRB is the best way to point the snorkel and why answer me that little one. :wink: Before I reach for the screw driver and have a little fiddle.
The pest might make waves but do the waves stimulate ideas and discussions or just make your feet wet at the seaside. :?
All the best Arightpest
Range Rover Blues:
Mine points forewards and I disconnect it for the highway. It's a Safari and it was designed to point forewards.
Interesting discussion this guys, I like it, buit don't go asking me to do maths, I havn't read that book in years and I'm not sure where it is. I have a little experiment planned that should give us some reliable data. All I need now is a fine, dry, calm day, a Land Rover with a snorkel, some clear fishtank tube, a small cup of Ribena, oh and Tim to finish his exams and come help me out :wink:
Tyke:
Are you setting up a manometer to measure the pressure via a column of ribena . . . . certainly sounds like it from your shopping list ? :lol:
As for the maths . . . . . ditto . . . . . I had access to CFD software in my last job. would only need to model the system in 3D cad and plug in some numbers and it would have given us a solution in minutes. These days we don't much bother with the calculus, just plug in to the computer, the physics is the same though . . . . understand that and the fluid dynamics job is easy.
Anyone out there with access to CFD software, (Fluent, CFDesign, ect), that would like a look at this problem . . . I could provide suitable cad models.

You guys need to get out more :!:
