Summary

Heat transfer and pressure drop experiments are performed with water, at atmospheric pressure in the Prandtl number range 3.6-8.8, flowing in spirally indented tubes for heat exchanger applications. Large pitch geometrics are studied which minimize pressure drop. The tubes are tested in a counter-current flow configuration that produces results directly applicable to heat exchanger design applications. A data reduction technique is developed that is applicable to an arbitrarily augmented tube, and it is verified with the plain-tube data.
