| description abstract | To accentuate the imperatives of tackling the multitude of engineering as well as socioeconomic issues attendant to the energy–water nexus, he would often paraphrase the dilemma of the poet Samuel T. Coleridge,1 “Energy and water everywhere, but not a drop…….†The viability of heat transfer, and therefore enhancement or augmentation of heat transfer, in addressing the engineering challenges of this “energy crisis,†to use the popular idiom of the 1970 s, was foremost on his mind, and he tirelessly advocated the need for conservation along with research and application of advanced enhancement techniques in all heat and mass transfer systems. Because of his own pioneering work, which was extensive and spanned the spectrum of very small (micro/miniscale heat sinks, compact exchangers, etc.) to very large (power boilers, steam condensers, refrigerant heat exchangers, etc.) thermal systems, the field of heat transfer enhancement grew rapidly [1] and came to be regarded globally as a secondgeneration heat transfer technology.2 Arthur E. Bergles, or Art as he was known to us and his multitude of friends and colleagues all over the world, passed away on Monday, March 17, 2014, after an extended battle with a malignant brain tumor. He was 78 and leaves us a legacy of an exemplary, more than fivedecadeslong career marked with educational innovations, seminal and path breaking scientific contributions, and extensive professional service. | |
