A study was made on the natural convection heat transfer in insulated horizontal conduits. The gravity-induced flow in a long horizontal space of annular cross-section insulated laterally and with the two ends maintained at different temperatures was studied analytically. The velocity and temperature distribution in the central portion of the space was derived based on a perturbation analysis in the Rayleigh number.
