Brayton cycle: It is open cycle.

Rankine cycle: It's close cycle.

Brayton cycle: Mostly used in gas turbine engine.

Rankine cycle: Mostly used in power generation plant.

Brayton cycle: Resemble less to Carnot cycle.

Rankine cycle: Resemble is more to Carnot cycle.

The Rankine cycle is the fundamental thermodynamic underpinning of the Steam_engine. It is named after William_John_Macquorn_Rankine

Rankine cycle is used in steam turbine

carnot cycle is a very ideal cycle that isn't practical at all , 'cause we add and reject heat isothermally , a wet mixture enters the turbine so it'll cause pitting and erosion

and a wet mixture enters the pump , and the pump can't deal with a 2 phases fluid

rankine cycle is a practical cycle but with a very low efficiency

so the main difference lies in the adding and rejecting of heat

The four major components of the rankine cycle are as follows:

1. boiler

2. turbine

3. condenser

4. pump
