• This paper presents a detailed study of the heat transfer between concentric cylinders with an inner heated cylinder rotating and an outer cooled cylinder stationary. The heat transfer in the case of zero axial flow of fluid in the annuli was carefully measured for air, water, iso-buthyl alcohol and spindle oil with varying rotational speeds and annular gap widths. The heat transfer in the laminar plus Taylor vortices type of flow is analyzed with the assumption of constant physical properties. The heat transfer data confirm the existence of the critical Taylor number obtained theoretically for isothermal flow. The Nusselt number increases suddenly at the modified critical Taylor number and the theoretical results show a comparatively good agreement with the experimental ones. The simple empirical equation to fit well the heat transfer data over a wide range of Taylor numbers has been presented.
