See also, the Engineering Science Data Unit Design Guide ESDU 87019, which gives a clear explanation of mechanisms causing tube vibration in shell and tube heat exchangers, and their prediction and prevention. 

The Engineering Sciences Data Unit has also published a method for estimating shell-side the pressure drop and heat transfer coefficient, EDSU Design Guide 83038 (1984). The method is based on a simplification of Tinker s work. It can be used for hand calculations, but as iterative procedures are involved it is best programmed for use with personal computers. 

A procedure for estimating the shell-side heat transfer in horizontal condensers is given in the Engineering Sciences Data Unit Design Guide, ESDU 84023. 

The heat transfer coefficient at the inside wall and pressure drop through the coil can be estimated using the correlations for flow through pipes see Section 12.8 and Volume 1, Chapters 3 and 9. Correlations for forced convection in coiled pipes are also given in the Engineering Sciences Data Unit Design Guide, ESDU 78031 (2001). 

Data and design methods for wind loading are given in the Engineering Sciences Data Unit (ESDU) Wind Engineering Series (www.ihsedsu.com).

The Engineering Sciences Data Unit (ESDU) was set up to provide authenticated data for engineering design. Its publications include some physical property data, and other design data and methods of interest to chemical engineering designers. They also cover data and methods of use in the mechanical design of equipment. 

The effectiveness-NTU method will not be covered in this book, as it is more useful for rating than design. The method is covered in books by Incropera and Dewitt (1996), Ozisik (1985) and Hewitt et al. (1994). The method is also covered in the Engineering Sciences Data Unit, ESDU 86018 (1986). This reference gives large clear plots of effectiveness versus NTU and is recommend for accurate work.

The Engineering Sciences Data Unit (ESDU, www.ihsesdu.com) was set up to provide validated data for engineering design, developed under the guidance and approval of engineers from industry, the universities, and research laboratories. ESDU data include equipment design data and software and extensive high-quality physical property data—mostly for pure fluids that are in use in the oil and process industries.
