Abstract
Rotatable circular plates are stacked apart to form thin air layers therebetween. Rotation of the circular plates moves air over an air treatment material: catalyst or adsorbent. In one embodiment, the air treatment material is affixed to the surface of the circular plates. In another embodiment, the circular plates are formed from the air treatment material. The increased velocity of air relative to the circular plates causes separation of laminar flow, promotes boundary-layer turbulence near the plate surfaces, and promotes propagating stall in the air layers. These phenomena enhance the contact between the flowing air and the air treatment material.
