摘要：
An experimental investigation has been carried out to find the condensing side heat transfer coefficient, h(0), during condensation of steam over a plain tube, a circular integral-fin tube(CIFT) and a spine integral-fin tube(SIFT). The GIFT and SIFT have enhanced the h(0) by a factor of 2.5 and 3.2 respectively. The experimental values of h(0) for GIFT were compared with those predicted from different models. The Honda and Nozu model underpredicted the values of h(0) in a range of 10 to 20 percent. (C) 1998 Elsevier Science Ltd.
