Abstract

These experiments consisted of measurements of pressure losses and heat transfer rates for two unconventional crossflow heat exchanger configurations.

The first type consisted of an arrangement of circular tubes in a sawtooth pattern. Performance of this type did not appear to be an improvement over more conventional heat exchangers.

The second type used exchanger tubes of a special lenticular cross section so spaced as to keep the velocity of the fluid flowing outside the tubes nearly constant in magnitude reducing separation and drag. The lenticular tubes' performance was superior to the conventional types, especially at higher Reynolds numbers.
