Understanding the Concept of Gas Turbines

1. Closed Cycle Gas Turbine vs. Open Cycle Gas Turbine: A closed cycle gas turbine reuses the working fluid (gas) within a closed loop, which allows for better thermal efficiency due to reduced energy losses. Conversely, an open cycle gas turbine exhausts the working fluid, leading to potentially greater losses and lower overall efficiency.

2. Heat Recovery: Closed cycle systems can recover and reuse heat from the exhaust, maximizing the energy derived from the fuel and improving the overall efficiency of the turbine.

3. Comparative Analysis: When comparing both systems, closed cycle gas turbines generally demonstrate higher thermodynamic efficiency because they maintain the working fluid in a controlled environment, allowing for consistent and efficient energy conversion.

Final Answer

A closed cycle gas turbine gives higher efficiency as compared to an open cycle gas turbine.
