A direct numerical simulation is performed for turbulent heat transfer in a concentric annulus at Re D h ΒΌ 8900 and Pr ΒΌ 0:71 for two radius ratios (R 1 =R 2 ΒΌ 0:1 and 0.5) and wall heat flux ratio q Γ ΒΌ 1:0. Main emphasis is placed on the transverse curvature effect on near-wall turbulent thermal s
