non-moving aero grill blocks?
...just got my 1987 edition of HUCHO and while skimming through it, I thought about the patent(s) that Ford had on their new "belt" grills.
...has anybody studied the aero relationships between "sieve" and "shutter" effects of screen-mesh and flat-belt/bar grills?
• At what speed does a mesh-type grill (like the new Cadillac STS, etc.) switch over from acting like a sieve and begins to act like a shutter?
•Same question for the Ford bar grills?
...anybody know what the "describing" empirical equations might be for these two approaches to non-moving aero grill blocks?
