The innovation could reduce energy use in a variety of industries.
by the institution published on Tuesday. The researchers have found a way to improve at the same time the two key parameters that are conducive to the boiling process, the heat transfer coefficient and the critical heat flux .This is quite a development as there’s generally a tradeoff between the two, so anything that improves one of these parameters tends to make the other worse.
“If we have lots of bubbles on the boiling surface, that means boiling is very efficient, but if we have too many bubbles on the surface, they can coalesce together, which can form a vapor film over theThat film introduces resistance to the heat transfer from the hot surface to the water. “If we have vapor in between the surface and water, that prevents the heat transfer efficiency and lowers the CHF value,” the researcher added.
“These kinds of structures we’re making are not meant to be scaled in its current form,” she explained, but rather were used to prove that such a system can work.
