ABSTRACT

Condensation heat transfer results are presented derived from work carried out by NASA for the condensation of high velocity steam in downflow through a 7.44 mm ID copper tube. Overall parametric data, such as wall and coolant temperatures, local pressure, heat flux, quality and heat transfer coefficient are included and analysed in this paper. The flow development effects are shown to be significant in the determination of local characteristics (e.g. pressure and heat flux). Thus, a complete prediction of the flow may be necessary in order to achieve accurate estimate of local values.
