sci.adiabatic-flame-temperature Calculator
Calculates the adiabatic flame temperature from fuel heating value, air-to-fuel ratio, and specific heat of combustion products. Stoichiometric methane-air: T_ad ≈ 2,230 K — actual flame temperatures are 200–400 K lower due to dissociation of CO₂ and H₂O at high temperatures.
Inputs
Lhv Mj Kg
Reference formula or conversion factor shown for context.
Air Fuel Ratio
Reference formula or conversion factor shown for context.
T Initial C
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
Cp Products
Reference formula or conversion factor shown for context.
Results
adiabatic flame temperature Tad (°C)
The value at the specified point or condition.
temperature rise ΔT (°C)
The value at the specified point or condition.
stoichiometric AFR estimate
The value at the specified point or condition.
T_ad = T₀ + LHV/(m_mix × Cp)
Reference formula or conversion factor shown for context.
excess air factor λ
A dimensionless multiplier applied in the calculation.
