The Brayton cycle is a thermodynamic cycle that describes the operation of a gas-cycle engine, primarily used in internal combustion engines. It is a closed-loop system that consists of four processes that involve the transfer of energy between hot and cold reservoirs.
The first process is isentropic compression, where the gas undergoes a gradual decrease in temperature and pressure during compression. This is an adiabatic process, meaning that no work is done during this process.
The second process is isentropic expansion, where the gas undergoes a gradual increase in temperature and pressure during expansion. This is also an adiabatic process.
The third process is a power stroke, where the gas undergoes a cycle of expansion and compression, resulting in the generation of power. During this process, the gas is mixed with air and ignited, creating a spark that drives the piston.
The fourth process is isentropic cooling, where the gas undergoes a gradual increase in temperature and pressure during cooling. This is also an adiabatic process.
The Brayton cycle is an idealized model of a real gas-cycle engine and is used to calculate the efficiency of internal combustion engines
