Subject: vanagon tech data request for CFD (pretty nerdy)
Content-Type: text/plain; charset=us-ascii
Hello list,
I tried to search the net for a couple random bits of
tech data on the vanagon (in particular, the westy),
but couldn't really find much of what i wanted, even
though i know i've seen it out there before.
Basically, i grabbed my work computer for the long
canadian weekend and am supposed to be learning a CFD
(computational fluid dynamics) software, and figured
what better thing to analyze than how the wind passes
over the van and how heat is swept away...
Yes, i know i am a geek.
Anyway, what i need for now is two things:
1) Body dimensions - overalls are necessary, but i
would also like to include the geometry of the
radiator, with the duct behind that, and also the
engine/transmission compartment area.
2) Relative heat dissipation (best guess) of the
engine and radiator. Something along the lines of
assuming 90hp, x% efficiency = "y"hp waste heat, then
however this is divided between the radiator and the
actual engine itself. I'll probably make a best guess
(which won't be all that good) so it would be nice to
have one of you feed me some more reliable numbers.
For those who care, i'm going to approach this as a
series of 2D problems, just taking a slice of the
middle of the van (between driver and passenger) to
give a representative view of how the air flows over
and through the vehicle. I might also do another
slice somewhere along the length of the van to see how
air flows around the sides, but that'll get kind of
tricky since there is no symmertry that way. I'd
probably have to go 3D for that, and i don't think i
have the time right now to wait at least half a day
for the analysis... especially since i am supposed to
be doing "real" work :-)
Anyway, i know this is kind of an odd request, but i'm
pretty sure some of you might be interested. Also, i
think the software that i am using (CFDesign) has a
free viewer you can download, so if someone wants to
host the results, people can view and manipulate the
results on their own...
Thanks for reading this far,
-Damon
