The objective of this research is to develop comprehensive constitutive models for the hydrodynamics of flows at oblique angles in rod arrays, and determine their impact on design and performance analysis of heat exchanging components. The constitutive parameters are for single-phase flow the solid-fluid flow resistance, and for two-phase flow the phase flow resistances and relative phase motion. This report covers accomplishments of three tasks: (1) superposition models, data, and correlations for multi-dimensional, single-phase flow resistance are reviewed and compared; (2) two-phase flow observations and an individual bubble trajectory model for oblique flows are presented; and (3) single-phase flow analyses of several baffled heat exchangers were performed to determine the sensitivity of calculated pressure and flow fields to the choice of superposition model.
