From dew at dawn to a foggy mirror after a shower, condensation is part of our daily lives on Earth. In space, microgravity alters how heat flows through gases and liquids, a potential enemy for ...

When water vapour spontaneously condenses inside capillaries just 1 nm across, it behaves according to the 150-year-old Kelvin equation – defying predictions that this pre-quantum-era formula would ...

Water vapor from ambient air will spontaneously condense inside porous materials or between touching surfaces. But with the liquid layer being only a few molecules thick this ubiquitous and important ...

Experimental data on flow patterns and pressure drop in two-phase gas-liquid flows through a packed bed obtained aboard the International Space Station (ISS) are analyzed in the limit of low flow ...
