Abstract: In one aspect, a diffuser for expanding the cross-sectional area of an airstream comprises an inlet comprising an inlet cross-sectional area and an outlet comprising an outlet cross-sectional area. The outlet cross-sectional area is greater than the inlet cross-sectional area. A curved sidewall extends from the inlet to the outlet and at least partially defines an inner passageway. The curved sidewall comprises a convex portion and a concave portion. The convex portion is adjacent the inlet and the concave portion is adjacent the outlet.
