| Abstract | ||
| Convection heat transfer in horizontal channel filled with saturated packed bed has been studied numerically using finite difference technique. The channel wall is heated at constant heat flux and packed with a fluid – saturated spherical ceramic for diameter ratio (0.287). Air , helium and carbon dioxide are used as working fluid at Reynold number ranging (100 – 2500). The results show a significant effect of varying prandtle number on heat transfer rate and friction factor at different Reynold number. The radial temperature profile increase as the prandtle number decrease. The heat transfer rate increase as the prandtle number increase , Carbon dioxide is greater than for air and the last is greater than that for helium at the same flow conditions . Friction factor proportional inversely with prandtl number. New Correlations are obtained in this work: Nuav = 24.548 Re0.238 Pr0.0787 F = 39.1917 ( d Re 1−φ )0.901 | ||
