Agnirva Space Premier League - Expedition #32581: Boiling in Space: Understanding Two-Phase Flow for Advanced Space Systems

Heat transfer is a crucial part of many technologies, and it's especially important in space, where traditional cooling systems don’t work the same way as on Earth. The Interfacial Behaviors and Heat Transfer Characteristics in Boiling Two-Phase Flow experiment aimed to tackle this challenge by studying how boiling behaves in microgravity.

On Earth, gravity helps separate the liquid and gas phases during boiling. Bubbles rise, carrying heat away. But in space, there is no buoyancy force to help bubbles move, so the boiling process changes drastically. Understanding these changes is critical for designing efficient thermal management systems in spacecraft, life support modules, and future space habitats.

Conducted over multiple ISS expeditions, this study used a special experimental module to observe how bubbles form, grow, and move when a liquid is heated. High-speed cameras and sensors recorded these processes, allowing scientists to analyze bubble dynamics, heat transfer efficiency, and the formation of stable vapor-liquid interfaces.

Results from this research help improve the design of heat pipes and other cooling devices used in satellites and space stations. It also provides foundational knowledge for developing thermal systems for lunar and Martian bases, where controlling heat in low-gravity environments is a major engineering hurdle.

This experiment is a perfect example of how applied physical science can pave the way for sustainable space living. It brings us one step closer to making long-term human presence in space a reality.
