Agnirva Space Premier League - Expedition #30821: Studying the Fine Details of Space Boiling: RPI's Contribution to FBCE on the ISS

The Flow Boiling and Condensation Experiment (FBCE) has been a monumental endeavor on the International Space Station, and the Rensselaer Polytechnic Institute (RPI) has played a critical role in deepening its scientific reach. Under the guidance of Dr. Joel Plawsky, this branch of the FBCE explores intricate aspects of heat transfer under microgravity, contributing to a holistic understanding of how fluids behave in space.

What sets this study apart? While FBCE as a whole examines boiling and condensation, the RPI-led segment zeroes in on detailed analysis of surface properties and fluid dynamics at the microscopic level. The goal is to determine how surface textures, temperatures, and fluid types influence the efficiency of heat transfer. In space, these insights are crucial for designing reliable thermal control systems.

This work, conducted during Expedition 68, employs advanced diagnostics to capture fluid behavior in real time. Cameras and thermal sensors monitor the onset of boiling, bubble nucleation, and condensation processes. RPI’s approach focuses on correlating these behaviors with surface engineering—a step that could lead to custom-designed heat transfer surfaces tailored for space environments.

Beyond the ISS, the data have broad terrestrial applications. They inform the development of high-performance cooling systems for electronics, renewable energy setups, and industrial processes. By understanding how heat behaves in extreme environments, engineers can push the boundaries of efficiency and safety.

The RPI extension of the FBCE project exemplifies how academic institutions contribute to space research in meaningful ways. Their findings enrich the FBCE dataset and expand its impact, both in orbit and back on Earth.
