The mass flow rate through the nozzle of a turbojet engine is a critical parameter that plays a significant role in the engine’s performance. The nozzle of a turbojet engine is responsible for accelerating the high-velocity, high-temperature exhaust gases generated by the combustion process, ultimately producing thrust. The mass flow rate through the nozzle can be defined as the amount of air and combustion products that pass through the nozzle per unit of time. It is typically measured in kilograms per second (kg/s) or pounds per second (lb/s).
The mass flow rate through the nozzle (M_dot_nozzle) can be calculated as:
Where:
- ṁinlet = Inlet Mass Flow Rate
- ṁfuel = Fuel Flow Rate
