PRESSURE DROP AND HEAT TRANSFER FOR FLOW OF BOILING WATER IN VERTICAL ROD BUNDLES
Abstract
Pressure drop and beat transfer for upflow of boiling water in vertical multi-rod bundles are analysed in the report. The rod bundle is considered as a system of parallel interacting sub-channels. In the technique proposed the void formation over subcooled boiling region is taken into account as well as the nonsimilarity of the subchannel and tube geometries. A short description of the 6 MW rig and some experimental results from the 19-rod bundle are given.
