Pulsejet engines are a type of air-breathing jet engine known for their simple design and intermittent combustion process. They operate on the principle of utilizing shock waves and pressure variations to generate thrust. Pulsejet engines don’t have a traditional nozzle Inlet like in turbojet or rocket engines, but the total energy at the exit can still be considered.
The total energy () at the nozzle Inlet can be expressed as:
where,
- E is the Total Energy, i.e sum of kinetic and potential energy
- Â is the Static Enthalpy at nozzle Inlet,
- Â is the velocity of the incoming air relative to the reference frame of the engine
