WebThe heat engine absorbs heat energy from a higher temperature source and transfers it towards a lower temperature source, i.e., the surrounding sink, by producing work. The Kelvin-Planck statement is the foundation of the heat engine—for example, gas and steam turbines, gasoline and diesel engines. WebHeat Engines in the Real World. All undergraduate physics students are taught the Carnot cycle as an example of a thermodynamic engine. The Carnot cycle is optimized for efficiency but unfortunately yields zero power, and is therefore not very useful in reality. However, it’s analysis is mathematically elegant.
