1. An air circulation system configured to mount within a B-pillar of a vehicle, the air circulation system comprising:
a scroll within the B-pillar, the scroll defining an inlet configured to receive inlet air from a vehicle cabin at the B-pillar;
a fan within the B-pillar and configured to circulate the inlet air within the scroll;
an elongated throat extending from the scroll and configured to receive forced air from the scroll, wherein the throat defines a length and an outlet extending along the length, wherein the outlet is configured to deliver the forced air into the vehicle cabin from the B-pillar in an air stream; and
a deflector pivotally attached to the throat, wherein pivoting of the deflector changes the direction of the air stream;
wherein the outlet is configured such that the forced air delivered from the outlet creates a Coandă effect that attracts air in the vehicle cabin to move in the direction of the air stream; and
wherein the throat defines an outer surface having a concave region extending along the length of the throat, and the deflector is pivotally attached to the throat within the concave region.
