- Abstract
- A mixture fraction formulation is used to numerically simulate the structure of diluted axisymmetric methane-air nonpremixed counterflow flames. the effects of global strain rate and gravity were investigated and results were compared. Fuel of a mixture of 20% methane and 80% nitrogen by volume and oxidizer of pure air at low and moderate global strain rates in normal and zero gravity were computed. It is shown that the numerical method is capable of predicting the structure of counterflow flames in normzl and microgravity environments at low and moderate global strain rates.
