In combustion physics, fuel mass fraction is the ratio of fuel mass flow to the total mass flow of a fuel mixture. If an air flow is fuel free, the fuel mass fraction is zero; in pure fuel without trapped gases, the ratio is unity.^[1] As fuel is burned in a combustion process, the fuel mass fraction is reduced. The definition reads as

${\displaystyle Y_{F}={\frac {m_{F}}{m_{\rm {tot}}}}}$

where

• ${\displaystyle m_{F}}$ is the mass of the fuel in the mixture
• ${\displaystyle m_{\rm {tot}}}$ is the total mass of the mixture
