Heat release parameter

In combustion, heat release parameter (or gas expansion parameter) is a dimensionless parameter which measures the amount of heat released by the combustion process.[1][2] It is defined as

where

  • is the burnt gas temperature
  • is the unburnt mixture temperature.

In typical combustion process, . For isobaric combustion, using ideal gas law, the parameter can be expressed in terms of density,[3] i.e.,

The ratio of burnt gas to unburnt gas temperature is
