Nozzle Mass Flow Rate of a Ramjet Engine

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.

The mass flow rate ṁ through a ramjet engine nozzle can be expressed as:

Where:

• ṁ is the mass flow rate (kg/s),
• $\rho$ is the density of the air (kg/m³),
• $A$ is the cross-sectional area of the nozzle (m²),
• $V$ is the velocity of the air through the nozzle (m/s).
