IHS ESDU Design and performance evaluation of heat exchangers: the effectiveness-NTU method. Part 3: graphical and analytical data. 98005

ESDU 98005 provides graphical and tabular effectiveness - NTU data for a wide range of practical heat exchanger configurations. The data are presented in "family groups" based on exchanger types, and for each family group there is an Index of Geometries, within which each particular configuration (which may cover a range of practical heat exchangers) is identified by a concise description and a unique acronym. A data sheet is given for each configuration including graphical information and a detailed description. The description includes where available the mathematical relationship between E, NTU and C* (the stream thermal capacity ratio) and its source, notes on the derivation of the data, maximum and asymptotic effectiveness data and expressions, a curve for the temperature meet, and the coefficients of an algebraic expression for effectiveness that has been fitted to the data for most configurations. Data are provided for a wide range of single- and multi-pass crossflow configurations (including serpentine), single- and multi-pass E- and J-shells, trains of E- and J-shells, single F-, G- and X-shells, and single- and multi-pass plate-type configurations. ESDU 98003 describes the method and introduces the data presented here and in ESDU 98004 where the data are in a convenient form for selection purposes. The use of the method is illustrated in design studies in ESDU 98006. Analytical techniques used to derive the data are described in ESDU 98007.
