ABSTRACT

In this work, the eccentricity effect on heat transfer in an annular square filled with a saturated porous medium was investigated. A numerical solution based on the Galerkin finite element was found for three different cases: (1) positive and negative diagonal eccentricity, (2) positive and negative horizontal eccentricity ±ex, and (3) positive and negative vertical eccentricity. In this study, the outer walls of the annuli were kept isothermally at hot temperature, while the inner walls were kept isothermally at cold temperature. The analysis is carried out to find the influence of eccentricity for three selected nondimensional values (±0.1, ±0.5, ±0.9) on two selected Rayleigh numbers of 100 and 200, without and with the effect of radiation equal to 0 and 1 and for different width ratios (0.25, 0.5, 0.75), respectively. Numerical results of fluid flow and heat transfer characteristics inside the porous medium for the three cases considered were presented and discussed. Furthermore, the results of the average Nusselt number of each outer wall show an increase as eccentricity increases, in particular, at higher values of width ratios ≥0.75.
