The heat release rate in a combustion chamber is a critical parameter in aircraft engine design and analysis. It represents the rate at which heat is released due to the combustion of fuel.
The formula to calculate the heat release rate can be defined as follows:
- Heat Release Rate (HRR) is the rate at which heat is released, typically measured in watts (W) or joules per second (J/s).
- Mass Flow Rate of Fuel is the rate at which fuel is being injected into the combustion chamber, typically measured in kilograms per second (kg/s).
- Heating Value of Fuel is the amount of energy released per unit mass of fuel during combustion, typically measured in joules per kilogram (J/kg).
