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

\alpha ={\frac {T_{b}-T_{u}}{T_{b}}}

where

$T_{b}$ is the burnt gas temperature
$T_{u}$ is the unburnt mixture temperature.

In typical combustion process, $\alpha \sim 0.7-0.9$ .
