Parametric study and field synergy principle analysis of H-type finned tube bank with 10 rows
چکیده انگلیسی

In this paper, three-dimensional numerical studies are performed for heat transfer and pressure drop characteristics of H-type finned tube bank with 10 rows by software FLUENT. The effects of seven geometric parameters (tube row number, fin thickness, slit width, fin height, fin pitch, spanwise tube pitch and longitudinal tube pitch) and Reynolds number are examined. It is found that for the tube bundle studied, the heat transfer and fluid flow are in the developing region, and they become periodically fully developed after the 10th row. Among the seven geometric parameters spanwise tube pitch has the most important effect and slit width has the least important effect, with other five parameters in between. The results are also analyzed from the view point of field synergy principle. It is found that the effects of the eight parameters on heat transfer and fluid flow characteristics can be well described by the field synergy principle. Correlations of Nu and Eu for the 10-row tube bundle are presented.
