  Lecture 22: Introduction
 


Analysis of 1D Flame

Continuity Equation

:

State Equations:

Momentum Equation

:

Energy Equation

:
       
are the density, velocity, pressure and temperature
q is the heat release per unit mass
is the mass fraction of species
heat of formation of species

Combining Continuity and Momentum Equations and expressing them in terms of Mach number,

 

Rearranging the energy equation, we can get
