摘要：An analytical solution for natural heat transfer in a cavity filled with air between two concentric cylinderswith half insulated cavity and low Rayleigh number presented in the present work. Solution based on Perturbationmethod with two terms for both temperature and streamlines values. Variables taken in present work are; radii ratio,temperature difference between inner and outer tubes, and changing tilt angles. Solution of present work shows a goodagreement with numerical solution of a near problem. Validity of solution led to show more results. Nusselt numbershow to increase as tilt angle increased, while local Nusselt number varies according to velocity pattern andtemperature distribution.
