Abstract

The coupled non-linear PDEs modeling developing laminar mixed convection in a horizontal tube and conduction in the surrounding solid have been solved numerically for bare and finned tubes. The results, for heat losses varying linearly with the temperature of the solid, show that the corresponding thermal and hydrodynamic fields are quite different and that the heat loss from the top fins is significantly greater than that from the bottom fins.
