I think that it probably fell foul of the number of surfaces regulation that has persuaded Mercedes to shape their side-pod/wing combo as it is. I thought that it was a very interesting detail in the car at launch.
I don't think that it does. The forward sidepod volume is a separate volume than the coke panel volume. It's this transition region that permits both the Merc mid wing and this Williams porthole. However, it does fall afoul of the coke panel minimum cross sectional radius and continuity rules. It gets around this by exploiting the louver allowance, imo.
It does seem to fall within the louver aperture allowance zone (compare to Renault in jpg below). Does it satisfy the requirements of a louver? I think it might, although it would depend upon how 'cooling flow' is defined.
b. For the sole purpose of allowing cooling flow exits, apertures may be added provided they lie within RV-RBW-APERTURE. The total area (per side of the car) of such apertures may be no greater than 150,000mm2. Furthermore, any apertures added must be arranged such that, when viewed from above, no part of RS-RBW-APERTURE may be visible through the aperture and any underlying part of the car exposed by application of an aperture must lie no further than 50mm normal to the untrimmed surface.
