• The phenomena of droplet shattering on spacer grids is an important consideration in two-phase heat transfer in rod bundle geometries. Droplet breakup over grid straps enhances the downstream heat transfer be increasing the available surface area for evaporation to occur. A rod bundle geometry consisting of 49 rods connected with mixing-vane spacer grids and an overall length of 3.7m (144 in) was used to quantify the behavior of droplets as they pass over a spacer grid. The experiment involved the use of a system called VisiSizer, which is a digital imaging system, to determine the droplet diameter distributions upstream and downstream of a spacer grid. The results show that the spacer grids produced a 29% decrease in the mean diameter of the droplets at the given experimental conditions. This compares well to previous experiments conducted on droplet shattering.
