This paper is concerned with heat exchangers having continuous, flat fins on a staggered
array of circular tubes. Correlations are developed to predict the air-side heat transfer …

This paper deals with heat exchangers having plain fins on a staggered array of circular
tubes. Correlations are developed to predict the air-side heat transfer coefficient and friction …

Data are presented for nucleate pool boiling on five different horizontal tube geometries using
five refrigerants at two saturation temperatures. The refrigerants tested are R-11, R-12, R-…

Because of the low heat transfer coefficient of gases, it is necessary to use extended surfaces
on the gas side when exchanging heat with liquids or two-phase fluids. Such finned tube …

… This study extends previous work of Bergles and Webb to establish a broad range of
Performance Evaluation Criteria (PEC) applicable to single phase flow in tubes. The equations …

… The authors provide an empirical modification to the Schmidt equation (Hong and Webb …
Use of the sector method with the Hong and Webb equation is recommended. Cases for …

This paper surveys the evolution of special surface geometries that promote high-performance
nucleate boiling. Early work by Jakob and Fritz in 1931 showed that emery paper …
