Experimental Study on Condensation Heat Transfer of Steam-Air Mixture on Large Tube Bank

摘要

Condensation heat transfer of steam-air mixture on large tube bank was investigated experimentally for wide inlet steam mass fraction range of 10-50wt%. The tube bank consisted of 24 staggered rows of two tubes per row. Experiments were performed by using mixture of saturated steam and air under atmospheric pressure. Measured heat transfer rates were compared with the calculated values by the relation of simple heat and mass transfer analogy.
