Anyone familiar with aerodynamic computer models?

I found a piece of software that lets you run aerodynamic tests on models. https://www.simscale.com/ I was wandering if anyone was experienced in making said models so we could start to look at and improve the aerodynamics of our cars. If there are any pre-existing models that would be nice.

Thanks that's pretty helpful. Expensive though. I probably wouldn't be allowed to use them though because the program they use uploads the model for free to the public.

I will be getting the headlight covers for sure. I don't really want to change the appearance of the car though. Other then the grill maybe. I have the fish mouth grill.

I read somewhere that the the RB MGB is the most aero.

Where has it been done before? Were the results really so good that no one else should try? I would applaud efforts that would improve the aerodynamics of the GT windscreen area, and therefore reduce wind noise. A gentleman with experience in this profession tried it a few years ago and as I recall he concluded that making the MGB less noisy from a physical and aerodynamic standpoint was not worth it. He got minimal improvements over the course of many experiments. I suppose these are simply noisy old cars that weren't designed to travel 80MPH all day long, like most old cars! winking smiley I know about the Works and privateer efforts to improve speed and efficiency on the track, but I haven't seen anyone do an in-depth computer simulation on aerodynamics. I say go for it!

Adam,

I believe the aero discussion starts with comment 1112

Thanks I'm reading through it all now. Looks like there are a couple of things that I could do to improve the aerodynamics. I'm not really looking at down force at the moment but just looking to streamline the car in small ways. I think the front could be better and the bonnet could use a re-design. Apparently the MGC bonnet with the bulge in it helps keep the air away from the windshield which isn't angled down very much. I might look into that. And the rain gutters need something done to them probably.

I kind of do like the drop nose. Without an air dam, it is likely to fly though. With one, it would not be as pretty.

They no longer list it as available. Their current product is here:

Of course, strait line speed is not all there is to aerodynamics.

The aforementioned study included rain gutters, which were assumed to be a large part of the wind noise issue. Smoothing them did almost nothing, unfortunately.

I have just been reminded of wind deflectors, from the dark ages. They were like a mini snow plow and bolted to the front of the bonnet (hood). Supposed to reduce wind drag on the windscreen. I tried to find a picture, but no luck.

Herb, try a Google image search for "Old Bug Deflector".

I think if you get a bonnet with a bulge in it, it will deflect more of the wind away from the windscreen.
