Gas Turbine What is gas turbine? How important is the gas turbine to the engineering applications? How does the gas turbine work? What is the performance of the gas turbine ?

Introduction Fluid machinery Fluid machine that adds energy to the fluid is called, pump, compressor, blower or fan. Fluid machine that extracts energy from the fluid is called turbine.

Introduction Fluid machinery For fluid machines of dynamic type, the machines can be further divided according to the flow direction (respect to the rotating shaft) as The radial flow machine: radial flow compressor, radial flow turbine. The axial flow machine: axial flow compressor, axial flow turbine. The mixed flow machine.

Introduction Gas Turbine Gas Turbine is usually referred to a unit consisted of compressor, combustion chamber and turbine. Gas Turbine convert heat energy of a fuel into mechanical energy.

Piston engine vs Gas turbine engine

Advantages: Gas turbine engines have a great power-to-weight ratio compared to reciprocating engines. The flow of the fluid in the process can be classified as steady flow. Disadvantages: The main disadvantage of gas turbines is that, compared to a reciprocating engine of the same size, they are expensive, and they prefer a constant rather than a fluctuating load.
