Amongst which of the following gas turbines isolates and reuses the working fluid?

12. Amongst which of the following gas turbines isolates and reuses the working fluid?

1. Open-cycle Gas Turbine
2. Closed-cycle Gas Turbine
3. Semi-closed Cycle Gas Turbine
4. None of the above

Answer: B) Closed-cycle Gas Turbine

Explanation:

Instead of the surrounding air, the closed cycle gas turbine uses working fluids such as helium and hydrocarbon mixtures, which internally go through some thermodynamic cycle within the closed loop, resulting in the reuse of the working fluid.
