Flow Illustrator shows that Inchul Kim/Metacomp spoiler works nicely!

So far I don't know how to "copy" videos generated by Flow Illustrator (please show me how) so I posted the bitmap images it requires

Its bitmap image

A teadrop Kamm without spoiler

And with the spoiler


A top-down convertible car with the spoiler on the windshield header

I believe the spoiler can also help reattach underbody flow.

The same car without such spoilers


The bare spoiler

By the way How can you overlap a car and this spoiler image without having Photoshop to trim the borders?
Is there any nice, free and easy to use software to trim the spoiler image edges paste it over a car image?

So far I've only used Power Point to overlap images but I got something like this

So I need an imaging software

I truly believe this spoiler has the potential to help reattach and redirect flow as to reduce its wake cross sectional area.

This may be used in the backlight header, backlight sides, under the rear bumper and in trunk rear outer edges integrated in the bodywork.

According to the article:

aerodynamic drag and lift on a mini-van moving at 108 kph (67 mph)...............bluff-backed vehicles.............

I think that outside of the applications listed above you are in a very gray area.

For instance most of the locations you show would do little to help and may even harm the aerodynamics.

The top of the windshield location has been discussed in a another thread. I am doubtful to it's usefulness here.

The patent drawing looks to be a similar profile to a teadrop Kamm, but I suspect that was a precaution to insure it worked at all prior to testing.
