Adaptive cycle engines are specially designed to alternate between efficiency and raw power—extending an aircraft’s range ...

The key to understanding the proposed LNG revaporization processes that follow is that the temperature difference between the heat source (a→a’) and the heat sink supplied by the liquid methane (1→4) ...

“We’ve developed the world’s smallest steam engine, or to be more precise the smallest Stirling engine, and found that the machine really does perform work,” said Clemens Bechinger, a physicist at the ...

A thermodynamic analysis based on a pressure-time history measured during the combustion in a SI engine is a commonly used tool used for analyzing the combustion process. Both one-zone and two-zone ...

The quantum advantage: Coherent superposition in quantum heat engines can enhance power output over classical machines. Credit: iStock Traffic-Analyzer Heat engines have had a huge impact on everyday ...

Power boost: a quantum heat engine in synthetic diamond. (Courtesy: Jonas Becker) Physicists have in recent years built a number of microscopic heat engines to investigate how the laws of ...

Heat is animus. It was there at the birth of the universe, and its death will be the universe’s death. It is impossible to overstate its importance — both throughout human history and across modern ...
