The mass flow rate through a divergent nozzle is the amount of fluid (gas) passing through the nozzle per unit time. In the context of a divergent nozzle, this nozzle geometry accelerates the flow, converting pressure energy into kinetic energy, and plays a crucial role in the performance of propulsion systems like rocket engines and jet turbines.
you can express the mass flow rate through a Divergent nozzle 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
