Effect of pressure on molecular gas properties in turbulent combustion

Qualitative and quantitative correspondence between calculations and experimental data is a means of evaluating the validity of the assumptions on which a theory is based. Mathematical modeling of turbulent combustion using differential balance equations for instantaneous parameter values in the one-dimensional approximation has made it possible to describe the effect of turbulence characteristics on combustion to some degree of accuracy and to introduce a detailed chemical reaction mechanism into consideration. The two-dimensional approximation allows verification of generalized equations in a significantly more realistic formulation. The present study will use that framework to consider the effect of pressure and the molecular properties of the fuel such as viscosity, thermal conductivity, and the value of the diffusion coefficient upon turbulent combustion.
