“…Finned tubes have been studied, for example, by Myers and Katz (1953), Wall and Park (1978), Danilova and Dyundin (1972), Hahne and Mueller (1983), , and Cornwell and Scoones (1988). Generally, these investigators found that the finned tubes exhibit the same behavior as previously obtained with smooth tubes, except for a higher starting basis due to area enhancement.…”
