dc.description.abstractThe problem of combined conduction with natural convection heat transfer in vertical concentric annuli has been investigated numerically using an implicit finite-difference scheme. Both the transient and steady-state heat transfer have been considered in this investigation. The effects of the three main controlling parameters, namely, modified Grashof Number (Gr*), thermal conductivity ration (KR) and thermal diffusivity ratio (αR) have been presented over wide ranges of these parameters. The study showed that KR and αR have prominent effects on the flow characteristics as well as on the heat transfer. Moreover, at the values of KR = 100 and αR = 1000 the conduction effect on the heat transfer becomes negligible and for such values the results of the conventional case can be used with an acceptable accuracy.
