Total Energy At Nozzle Exit For a Turbofan Engine Calculator

The total energy at the exit of a nozzle for a turbofan engine, similar to other propulsion systems, is a combination of enthalpy and kinetic energy. In the context of a turbofan engine, the nozzle exit refers to the exit of the nozzle guide vanes or stators, just before the gases enter the jet nozzle.

The total energy ($E$) at the nozzle exit can be expressed as:

where,

• E is the Total Energy, i.e sum of kinetic and potential energy
• $h$ is the static enthalpy at the nozzle exit,
• $V$ is the velocity of the exhaust gases relative to the reference frame of the exhaust gases
