Abstract
The problem of laminar free convective heat transfer in the annulus between two eccentric horizontal isothermal tubes was solved numerically using a variational finite element method. Emphasis was given to the effect of eccentricity on the heat transfer coefficient in the Rayleigh number range from 0 to 104 and for different diameter ratios. In the range of eccentricities and diameter ratios considered, the increase in the overall heat transfer coefficient, as compared to the concentric geometry, reached a maximum of 38%. However, as the Raleigh number increases, the effect of eccentricity decreases. The general criterion agrees with the experimental results of Kuchn and Goldstein [5] at high Rayleigh numbers. The overall heat transfer coefficient continues to be strongly influenced by eccentricity over a wider range of Rayleigh numbers for smaller diameter ratio annuli.
