AN ANALYSIS OF CONVECTIVE HEAT-TRANSFER TO LAMINAR DISPERSED FLOW IN ECCENTRIC ANNULI

Analysis is carried out for fully-developed, laminar dispersed flow heat transfer in eccentric annuli for post-dryout conditions where the inner wall is maintained at a constant temperature while the outer wall is insulated. The heat transfer contribution of saturated droplets in the superheated vapor stream is considered as distributed heat sinks. The size and the population density of the droplets are considered as constants. The results indicate no explicitly dependence of vapor temperature profile on the mean vapor temperature, which is different from previous investigations. The effects of the droplet characteristics on the convection heat transfer are studied for a wide range of eccentrities and radius ratios.
