Two-Phase Capillary-Pumped Loop: A Potential Heat Transport System

This paper presents the general objectives, the design concept and the potential performances of the two-phase capillary pumping loop (CPL) as a heat transportation system.

In particular the actual design of the ESA funded development program “CPL”, designed and developped by SABCA and DORNIER will be shown as well as of its development status.

Results obtained with the first breadboard CPL model are reported together with comparison of predicted against tested performances.
