In aircraft design and combustion analysis, “inlet velocity” in the combustion chamber refers to the velocity or speed at which air or the air-fuel mixture enters the combustion chamber. It is a critical parameter that affects the combustion process and engine performance.
The formula to calculate inlet velocity can be defined as follows:
- Inlet Velocity (V) is the velocity or speed at which the air or air-fuel mixture enters the combustion chamber, typically measured in meters per second (m/s) or feet per second (ft/s).
- Mass Flow Rate of Air is the rate at which air is entering the combustion chamber, typically measured in kilograms per second (kg/s) or pounds per second (lb/s).
- Air Density is the density of the air in the combustion chamber, typically measured in kilograms per cubic meter (kg/m³) or slugs per cubic foot (sl/ft³).
- Cross-Sectional Area is the area of the inlet or entry point through which air is flowing, typically measured in square meters (m²) or square feet (ft²).
