The mass flow rate through a ramjet engine nozzle is a critical parameter that influences the engine’s performance. A ramjet engine is an air-breathing engine that operates at high speeds, relying on the forward motion of the vehicle to compress incoming air and mix it with fuel for combustion.
you can express the mass flow rate through a nozzle for a ramjet Engine in Ideal Gas and Isentropic flow in terms of known parameters like pressures, temperatures, and throat area:
where,
- ṁ is the mass flow rate of the nozzle
- P is the pressure
- R is the gas constant for the working fluid
- T is the Temperature
- A is the throat nozzle area
- M is the Mach Number
- a is the speed of sound in the medium
