Click the image to see a 1.3 MB MPEG movie of smaller bubbles gathering into the large one. Surface tension effects cause the many small bubbles produced to coalesce into one large sphere. Left: Without buoyancy, the vapor produced by boiling simply floats as a bubble inside the liquid after the heating has stopped. Once it begins to boil, buoyancy sends bubbles hurling upward, creating a "rolling boil."Īll of this motion within the liquid makes the physics of the situation much more complex. When a pool of liquid is heated on Earth, gravity causes hotter regions in the liquid to rise, and cooler, more dense parts to sink - a process called "convection." This motion spreads the heat around inside the liquid. One thing space does for us is simplify the problem that we're studying," Chiaramonte says. You would also want to look at a simpler planet with fewer variables. "As an example, imagine you were trying to study the Earth, which has such complex ecosystems. It also provides a powerful tool for scientists who want to unravel the tangled physics of boiling. This difference explains why boiling liquids behave so differently in space. Weightlessness effectively removes two of the variables in boiling - convection and buoyancy. In the free-fall of orbit, boiling is simpler than it is on Earth. "The phenomenon of boiling is so complex that most of our understanding is empirical, rather than based on the solutions to fundamental equations," Chiaramonte says. Engineers designing the ISS cooling system used information gleaned from microgravity boiling experiments. Right: The International Space Station uses a "2-phase" cooling system in which ammonia changes from liquid to vapor and back, which involves boiling. Scientists can use this perspective to improve their understanding of the fundamentals of boiling, which might be used to improve the design of terrestrial power plants. The weightless environment gives scientists a new "window" into the phenomenon of boiling. The research could also have applications here on Earth. Knowledge of boiling in space might also be used someday to design power plants for space stations that use sunlight to boil a liquid to create vapor, which would then turn a turbine to produce electricity. Learning how liquids boil in space will lead to more efficient cooling systems for spacecraft, such as the ammonia-based system on the International Space Station.

Already, he says, the series of experiments has come to be regarded as "classic" by today's researchers.ĭespite its entertainment value, this research is much more than a simple curiosity. Francis Chiaramonte, who was the NASA Project Scientist for the Pool Boiling Experiment. "Think of it: no one had really seen boiling in space before these experiments - in the whole world, ever!" says Dr.
