This design manual presents methods to design and model the performance of key two-phase components in thermal management systems for spacecraft. Components for both capillary- and mechanically-pumped loops are modelled including: forced-convection evaporators, droplet evaporators; two- phase transport lines, fittings, and tees; shear condensers; capillary condensers; and mechanical pumps. Heat pipe condensers are also included. The methods can be used for component design and sizing, analysis of component performance in ...
This report documents two-phase fluid flow and heat transfer methods for microgravity environments. The applications of the work are thermal management, propulsion, and fluid storage and transfer systems for spacecraft. In the near future, these systems will include two-phase, vapor-liquid flows. This Design Manual is intended for use by designers of these systems. Design methods are presented for predicting two-phase flow regimes and pressure drops in pipe flows from earth ...
