Abstract: | Forced convection to hydrodynamically and thermally fully developed laminar flow in eccentric annuli is studied. Following Reynolds et al. [1], we determine the solutions of the energy equation which satisfy certain fundamental boundary conditions. These fundamental solutions can be superposed to satisfy a wide variety of boundary conditions. Exact solutions of the energy equation could not be found, so an approximate solution was determined. Nusselt numbers, wall temperature and heat fluxes, wall-fluid temperature differences, and mean fluid temperatures are presented for a wide range of eccentricities and radius ratios. It is believed that these results are accurate to within 1 per cent. |
