Two-Phase Fluid Thermal Transport for Spacecraft

Bubble formation from wall orifice in liquid cross-flow under low gravity

“…More efficient thermal control systems for space application are therefore needed to handle the increasing power requirements. Two-phase flow thermal control systems provide effective thermal transport in spacecrat_ (Eastman et al 1984), which is due to the higher latent heat of vaporization of fluids compared to their sensible heat. Two-phase cross-flow where the induced drag force strongly contributes to the bubble detachment (Kim et al 1994).…”

Modeling bubble and drop formation in flowing liquids in microgravity

“…The high operating power levels for future space applications require more efficient thermal transport techniques. Eastman et al (1984) proposed the replacement of conventional single-phase flow systems with two-phase flow systems to obtain more effective thermal transport in space. Two-phase systems including gadliquid and liquid/liquid contacting systems are common phenomena encountered in space applications, such as propulsion systems, power generation systems, cryogenic transfer and storage systems, life support systems, and other chemical/material process engineering systems.…”
