Liquid Fuel Combustion (Contd.)
Using eq.6, eq.8 becomes,
Elimination of the non-linear term simplifies the analysis. This simplification is known as Schwab- Zeldovich Transformation.
Dividing eq.9 by ,
– Heat input required for vaporization of droplet
– Mass fraction of species at the surface of the droplet
Conserved variable for oxidizer
,
– Heat input required for vaporization of droplet 
– Mass fraction of species at the surface of the droplet
