Hello All -
I'm not ready to post pics of my whole aero semi project yet. But I would like to solicit input, thoughts, and constructive suggestions regarding the aerodynamics of the hot engine compartment air exhaust vents.
Of course, one would normally not have a body panel protruding away from the body with a sharp cut-off at the rear. You would blend this area into the body to maintain undisturbed flow. But in this case, the skirts behind the steering tires are rolled inwards, and hot 200+ degree air will vent from this area. (fan-on temp is 230 degrees F.)
We will fiberglass a small flange around the perimeter of the vent openings, and add grills.
Do you think the outside body air traveling over the vent will merge successfully with the hot underhood air exiting from the vent?
I obviously do, because I built it this way. We have been too busy with other stuff to model it and run it on CFD yet.
We could always add an F1 Fence as the Ferrari did, but I am unsure if this would be necessary. Tuft testing will confirm any and all hypothesis.
