Effect of the Compression Ratio on the Performance of Different Strategies of the Gas Turbine

A clean and safe energy is the greatest challenges in meeting the requirements of green environment. These requirements given way the long time governing authority of steam turbine (ST) in the world power generation, and gas turbine (GT) will replace it. Therefore, it is necessary to predict the cha...
