Abstract

An experimental and numerical study is performed on natural convection heat transfer from a horizontal isothermal inner tube to a surrounding isothermal outer tube. Experimental results are obtained using a Mach-Zehnder interferometer and the governing equations are solved numerically using a variational finite element method. Emphasis is given to the effect of inner tube eccentricity and azimuthal angular location on the thermal field in the annulus. Results are obtained for air at three specific Rayleigh numbers in the transition regime, Ra = 5 × 10², 10³, 1.5 × 10³.
