Chemistry:Fuel mass fraction
From HandWiki
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
- [math]\displaystyle{ Y_F = \frac{m_F}{m_{\rm{tot}}} }[/math]
where
- [math]\displaystyle{ m_F }[/math] is the mass of the fuel in the mixture
- [math]\displaystyle{ m_{\rm{tot}} }[/math] is the total mass of the mixture
