Conventional baffled shell-and-tube exchangers, while having an excellent record of acceptance and functionality, have some notable limitations. In particular, the shell-side path is wasteful on pressure drop, limits maximum thermal effectiveness and encourages dead spots where fouling or corrosion may occur. This paper describes an advanced shell-and-tube design, known as the Twisted Tube® Heat Exchanger, which is inherently able to overcome these limitations in addition to providing the further advantages of tube-side enhancement and good tube support to reduce susceptibility to vibration. The paper compares the Twisted Tube ® exchanger with conventional and advanced designs.
