![]() Ambient air is used as a working fluid in the air side while hot water is used for the tube side. ![]() The heat exchangers are made from aluminium plate finned, copper tube. A total of 10 samples of fin and tube heat exchanger with a tube outside diameter of 9.53mm, transverse tube pitch of 25.4mm and longitudinal tube pitch of 19.05mm, having various fin pitches, number of tube rows and fin thicknesses, are tested in a well insulated open wind tunnel. International Nuclear Information System (INIS)Īn experimental study is conducted to investigate the effects of a fin pitch and number of tube rows on the air side performance of fin and tube heat exchangers having herringbone wavy fin configuration at various fin thicknesses. ![]() Effect of fin pitch and number of tube rows on the air side performance of herringbone wavy fin and tube heat exchangers
