A new boiling crisis criterion developed by MIT researchers predicts inefficiency and could lead to breakthroughs in energy efficiency, electronics cooling, and more.
Researchers at MIT have developed a new boiling crisis criterion that predicts inefficiency by considering factors like nucleation site density , bubble size, growth time, and detachment rate. This breakthrough could lead to advancements in various fields, including energy efficiency , electronics cooling, water desalination, medical diagnostics, and more. Matteo Bucci, an associate professor at MIT, emphasizes the importance of understanding boiling physics for these applications.
Bucci's lab has created innovative techniques to study boiling and heat transfer phenomena that have long hindered energy advancements. Boiling is crucial for many industrial processes, accounting for 80 percent of electricity-producing power plants and playing a role in space propulsion, energy storage, and computer cooling. Despite seeming straightforward, understanding boiling physics has taken ten years of research, as it's notoriously challenging to investigate in complex systems like nuclear reactors. To address this, Bucci's research lab has developed novel experimental methods. One key focus is addressing the boiling crisis, which occurs when rapidly developing bubbles create a vapor layer that hinders heat transfer. The new criterion, based on nucleation site density, average bubble size, and the product of average bubble growth time and detachment frequency, helps predict when boiling becomes inefficient
