ABSTRACT
Compact heat exchangers tend to replace other types due to high area-to-volume ratio, reliability and low cost of operation and maintenance, especially in nuclear applications, such as GCRs and AGCRs. Exchanger compactness requires high values of the heat transfer coefficients, especially if fluids are gases. Various types of heat exchange surfaces for gas type heat exchangers were designed by manufacturers. Complex geometry of such surfaces required to enhance the heat transfer rates require experimental data for developing heat transfer correlations. Tabulated heat transfer data available in literature together with geometric elements were used in order to develop heat transfer and flow friction correlations for several widely-used heat transfer surface types. Such correlations are an essential instrument in exchanger design and rating procedures as well as optimization. Coulburn-Reynolds and friction factor-Reynolds correlation were developed and the goodness of fit was verified.

Keywords: Heat transfer correlation, Pressure drop correlation, Plate fin heat transfer surfaces
