Diagram of a closed cycle OTEC plant. Closed-cycle systems use fluid with a low boiling point, such as ammonia (having a boiling point around -33 °C at atmospheric pressure), to power a turbine to generate electricity. Warm surface seawater is pumped through a heat exchanger to vaporize the fluid. The expanding vapor turns the turbo-generator.
In closed systems, the expense of the exchangers represents the largest cost of the OTEC plant, with a 100MW plant requiring 200 exchangers the size of 20 foot shipping containers. [ 9 ] In 2010, Makai Ocean Engineering was contracted to construct computer models to evaluate whether a Mist lift power generation plant would be competitive with ...
The ideal Otto cycle is an example of an isochoric process when it is assumed that the burning of the gasoline-air mixture in an internal combustion engine car is instantaneous. There is an increase in the temperature and the pressure of the gas inside the cylinder while the volume remains the same.
Because the net variation in state properties during a thermodynamic cycle is zero, it forms a closed loop on a P-V diagram. A P-V diagram's abscissa, Y axis, shows pressure (P) and ordinate, X axis, shows volume (V). The area enclosed by the loop is the net work done by the processes, i.e. the cycle:

After dedicating his life to fighting the regime of Assad, Mazen Al-Hamada did not live to see it fall. A symbol of resilience and courage, the famous Syrian activist was found dead in the ...
Differs from Otto cycle in that V 1 < V 4. Brayton: adiabatic: isobaric: adiabatic: isobaric Ramjets, turbojets, -props, and -shafts. Originally developed for use in reciprocating engines. The external combustion version of this cycle is known as the first Ericsson cycle from 1833. Diesel: adiabatic: isobaric: adiabatic: isochoric Diesel engine ...
Higher levels of omega-6 fatty acids often found in ultraprocessed foods may interfere with the immune system’s fight against cancer cells, a new study says. Certain foods may disrupt your body ...
