Thermal Control System for Space Experiment on Two-Phase Boiling Flow -I ; Analysis and Design of Condenser

Abstract

Design of condenser planned to be installed on boiling flow experiment on ISS was conducted. In this condenser, rectangular vapor tube was installed on flat type cold plate which had experienced on-orbit experiments. Arithmetic thermal model was constructed, which considered tube wall conductivity, heat transfer coefficient on condensation and cooling water flow. Specification of condenser which can condensate vapor of 400W was determined through analysis by this arithmetic model.
