The melting behavior of phase change materials (PCMs) is numerically investigated in rectangular, trapezoidal, and heptahedral enclosures equipped with identical V-shaped fins, under coupled ...

A study published in Physical Review Letters (PRL) details a "Gambling Carnot Engine" that researchers report can attain 100% efficiency while also improving power generation. The researchers present ...

Stochastic thermodynamics is an emerging area of physics aimed at better understanding and interpreting thermodynamic concepts away from equilibrium. Over the past few years, findings in these fields ...

When I began my power industry career years ago (initially in the chemistry lab of a coal-fired power plant), the criticality of proper chemistry control of steam boilers, cooling water systems, and ...

The original version of this story appeared in Quanta Magazine. If there’s one law of physics that seems easy to grasp, it’s the second law of thermodynamics: Heat flows spontaneously from hotter ...

“Anomalous” heat flow, which at first appears to violate the second law of thermodynamics, gives physicists a way to detect quantum entanglement without destroying it. If there’s one law of physics ...
