H型鳍片管束传热特性实验研究
Experimental research heat transfer characteristics of H-type finned tube bundles
摘要
Abstract
Extensive experiments on the heat transfer and pressure drop characteristics of H-type finned tube bundles were carried out. In the present study, 5 samples of H-type finned tube bundles with different geometrical parameters, including the tube diameter, fin height, fin pitch, transverse tube pitch and longitudinal tube pith were tested in a wind tunnel. Test results are compared with results calculated from the correlation in Soviet thermodynamic calculation standard of boilers. The corresponding correlations of heat transfer and friction factor for H-type finned tube bundles with the tube diameter of 38 mm are proposed based on the experimental results. The comprehensive heat transfer correlation for H-type finned tube bundles with different geometrical parameters is also established and the correlation can describe 96. 5% of the database with an error of ± 15% . Comparisons between two groups of existing experimental data in literature and results calculated from the correlations are shown. The maximum differences of the Nusselt number are 11% and 17. 7% , respectively. The present investigation provides a reliable basis for the design of H-type finned tube bundles.关键词
