Hi Paul,
I am interested in the side mount concept for the radiator and decided to
play around with some 2D CFD code for flow vizualization.  Here are some
results I thought you may like to see.  The model for the radiator is crude
but may give an idea what is happening.

What is interesting is that the flow through the "radiator" concetrates to
the right.  Also, note the flow eddy in the corner of the duct.  I plan on
running a model with a better transition here.  What do you think?  How
about the geometry, is it fairly accurate for what you had in mind?
Anything you want to see modeled?

The units are non-dimensional, and the names velocity and pressure are in
spanish - the code developers are spanish.  I attempted to represent a
velocity of 150mph and duct inlet of 8" by using a Reynolds number of 1E6.

Adios ;-)

Hey that is real cool looking stuff Dan. Major major break through here.
What and where did you get this software? Thanks a bunch. Looks like our years
of talking about this is beginning to get some interest in the air flow computer
visualization community.

"the flow through the "radiator" concentrates to  the right."
That is exactly what Kays & London maintains and I verified with full scale test.
That is also the rational for the simple 2D wedge shaped duct

Can you redo the simulation to this configuration? I am mostly interested
in configuration D without the exit duct but dumping into the free stream
as you show in your simulations.

When we get the inlet duct worked out we can add these cowl flaps.
This will be prime material for the ACRE NL web site with credit to you of course.

Good work Dan. Thanks a bunch.

Here is the ultimate configuration Dan. I am really pleased. This stuff
confirms the research we have been doing on these cooling  ducts for the 
last five years. Is this software capably of 3D simulations? Not that
we really need it. I am totally happy with 2D as I think it is
90% of what need for cooling ducts.
