Abstract: The effect of heat conduction in the wall on the effectiveness of rotary regenerators is described. In order to document the effect of wall conduction, it is assumed that the thermal conductance of the solid is finite, both parallel and perpendicular to the gas flow. Two parameters introduced for modeling conduction effects are the Biot numbers in the y(Biy) and x(Bix) directions. Our results show that for certain values of Bix and Biy, the effectiveness including wall conduction can deviate substantially from results obtained when wall conduction is neglected.
