IntroductionFluid machineryFluid 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.

IntroductionFluid machineryFor 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.

IntroductionGas TurbineGas 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

Piston engine vs Gas turbine engine

Piston engine vs Gas turbine engineAdvantages: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.
