Reducing turbulence in the chair
I have an 09 Enfield Bullet with a Cozy sidecar attached - the kind that looks like a Steib "cucumber" type of deal. I have been driving it for a year now, and its fun.
The only problem I have is that passengers get hit in the face with a whole lot of air flow and turbulence. I ride in a real Steib sometimes and there's virtually no turbulence in it, and among the differences I can see are the Cozy has a much taller windscreen and its about 4 inches narrower also.
So, I've tried duct taping cardboard in various configurations around and across the existing windscreen, but I still aggravate the passengers with the air (and no, I'm not going excessively fast - the turbulence is always an issue from 5 mph on up, and very bad around 40 mph and up). Its particularly troublesome for my 4 year old son, for whom I bought the outfit in the first place.
SO, my question - before I spend the rest of my days experimenting with cardboard, are there things I should know - geometry and aerodynamics and such - that will help me get to the solution quicker? Thanks!
Have you added something to the sides like a convertable with the windows up and the top down. That helped on my fathers Chevy convertible when we owned it.

I have no experience with your sidecar, but FYI: The original windshield on my Sportster was plenty tall but too narrow, resulting in the wind collapsing "on my ears" and shaking my helmet - but that was only above 45mph, and unsafe above 50mph. A shorter wider shield cured "most" of the problem on the bike side. Reckon some of the turbulence in the sidecar is coming off the bike/driver?

Also, how much wind turbulence is generated from the tug's shape? With my Goldwing/Escort rig there isn't much turbulence in the sidecar, but the sidecar creates more turbulence on the right side for me on the bike.
