Fuel mass fraction

Template:About Template:One source 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. As fuel is burned in a combustion process, the fuel mass fraction is reduced. The definition reads as

$Y_F=\frac{m_F}{m_{\mathrm{t}\mathrm{o}\mathrm{t}}}$

where

• $m_F$ is the mass of the fuel in the mixture
• $m_{\mathrm{t}\mathrm{o}\mathrm{t}}$ is the total mass of the mixture
