The Effect of Fin Height During Steam Condensation on A Horizontal Stainles Steel Integral-Fin Tube

摘要

Finlm-condensation heat transfer on horizontal stainless steel integral-fin tubes was experimentally studied to examine the effect of fin height. Experiemnts were conducted at both atmospheric and vacuum conditions on eigh stainless steel tubes with rectangular fins of nominal heights ranging from 0.2 mm to 1.5 mm. The fin spacing and fin thickness were kept constant at 1.5 mm and 1 mm respectivley for all the tubes. The tubes had a nominal inside diameter of 13.11 mm and nominal rooot diameter of 14.25 mm.
