The implications and challenges of enhanced heat transfer for the chemical process industries

摘要

This paper considers the many techniques that have been developed to enhance convective heat transfer,with the emphasis on heat exchangers found in the chemical process industries.A summary is given of the techniques that are effective for the various modes of heat transfer.Of particular interest currently is compound enhancement that involves the simultaneous application of several techniques,so as to produce an enhancement that is larger than te individual techniques operating separately.There are many experimental and analytical challenges that relate to obtaining and applying data.The current advanced enhancement represents third generation heat transfer technology.This technology will find increasing application in all industries.
