Abstract

Flow patterns, temperature distributions and steady-state rates of heat transfer across horizontal, atmospheric-pressure, air-filled annuli have been determined. The optimal positions of two, low-conductivity, radial baffles inserted across (i) a concentric cavity with the heat flowing outwards, and (ii) an eccentric cavity with the heat flowing inwards were identified. It is feasible to interpolate from the way in which the results for these two quite different heat-transfer systems are presented, what will happen for other pipe-in-pipe configurations.
