The comparison of various gas turbine inlet aircooling methods for various ambient condition trough energy and exergy analysis [PDF]

open access: yes, 2012
The strong influence of climate conditions on gas turbine behavior is well known. During the summer season the output of gas turbines falls to a value that is less than the rated output under high temperature conditions. Cooling the turbine inlet air can

Exergy sustainability. [PDF]

open access: yes, 2006
Exergy is the elixir of life. Exergy is that portion of energy available to do work. Elixir is defined as a substance held capable of prolonging life indefinitely, which implies sustainability of life. In terms of mathematics and engineering, exergy sustainability is defined as the continuous compensation of irreversible entropy production in an open ...
