Influence of Ribbed Cylinder Arrangement in Air Space on Intensity of Free Convection Heat Transfer

The paper contains the results of experimental research and comparative analysis of mean convective heat transfer of a single pipe of 55.6 mm outside diameter with aluminium rolled-on ribs at 16.8 ribbing coefficient of horizontal, vertical and inclined arrangements. Data have been obtained for a si...

description The paper contains the results of experimental research and comparative analysis of mean convective heat transfer of a single pipe of 55.6 mm outside diameter with aluminium rolled-on ribs at 16.8 ribbing coefficient of horizontal, vertical and inclined arrangements. Data have been obtained for a single row of vertically and horizontally arranged pipes and also for singles rows of two-, three-, four-, five- and six-pipes which are horizontally arranged one over another with a 70 mm interval.Results of the investigations have been generalized in the form of similitude exponential equations embracing the interval of Relay number (35...400) • 103. Horizontal arrangement of a pipe results in the highest intensity of convactive heat transfer. When the number of pipes in a row is more than five convactive heat transfer reaches the least value and then this index is practically unchangeable. Decrease in convactive heat transfer intensity is equal to 1.42- and 1.21-fold in comparison with one- and two-pipe row.
