Sensors for a system to control the liquid flow into an evaporative cold plate of a two-phase heat transport system for large spacecraft

Two-phase flow heat transport systems (thermal busses) for the Columbus Space Platform and the Space Station are expected to incorporate systems to control the liquid flow rates into the evaporative cold plates. Such a control system consists of a sensor that monitors the cold plate (performance), a control algorithm and an actuator i.e. a valve...

Theoretical investigation of the basic thermal performance of multilayer insulation blankets

The thermal performance of evacuated multilayer insulation blankets depends on three modes of energy transfer: radiation between the radiation shields, gas conduction m the residual interstitial gas and solid conduction via the contacting interfaces. The importance of the contributions of the three heat transfer modes depends on many parameters...
