Wärmeübertragung zwischen einer Wand und dispersen Gas/Feststoff‐Systemen

Heat transfer from a rigid wall to gas‐solid particulate systems. Considerable progress made in the last twenty years now permits a better understanding of heat transfer between a rigid wall and gas/solid particulate systems. The following paper reviews this progress. The heat transfer from a rigid wall to fixed, agitated, and fluidized beds as well as to fixed beds with fluid flow is discussed, and an example of indirect cooling of high‐capacity computers is given. In modelling, the concept of a contact and a penetration resistance in series is applied. The physical significance and the calculation of these resistances are discussed.
