摘要

The range of previous analyses based on laminar films has been extended to cover both laminar and turbulent films. The advantage of utilizing elongated elliptical rather than circular conduits, first predicted by the laminar model, has been confirmed in the present analysis. Elliptical conduits with vertical to horizontal axis ratio A/B ≥ 4 were found to enhance the overall transfer coefficients by some 20%. The calculated results are in good agreement with experiment.
