Conjugate Natural Convection: A Study of Optimum Fluid Flow and Heat Transfer in Eccentric Annular Channels

Figure 3

Present results of average Nusselt number along the outer and inner interfaces for cases 1. I and 1. O for conventional natural convection compared with those of Mokheimer [47], K_r = 1000, χ₂ = 0.5, δ_o = 0.002, δ_i = 0.001, N = 20, M = 20, NSO = 25, NSI = 25.
