Beschreibung
Zusammenfassung:	This invention relates to a sonic device (and a method) for enhancing a process involving a solid object and a gas, where the gas surrounds the object or at least is in contact with a surface of the object, the device comprising sonic means for applying a high intensity sound or ultrasound to at least the surface object, wherein the high intensity sound or ultrasound, during use of the sonic device, is applied directly in the gas that is also the medium through which the high intensity sound or ultrasound propagates to the surface of the object, whereby a laminar sub-layer at the surface of the object is reduced and/or minimized. The reduction of the laminar sub-layer provides increased heat transfer efficiency and/or increased catalytic speed and/or increased gas exchange.
