Abstract

Abstract Preliminary results are submitted covering heat transfer and pressure loss for fluids flowing through the shells of small shell and finned-tube heat exchangers in crossflow. These results are compared to the calculated performance of similar exchangers with bare tubes, and the comparisons noted. It is brought out that this type of exchanger can now be applied to duties where finned tubes heretofore have not been used, namely, where over-all heat-transfer rates for bare-tube service would be from about 25 to 250 Btu/(hr)(sq ft)(deg F). It is also pointed out that this type unit is not suitable for many services. Actual field experiences are related.
