Abstract

In a constant volume combustion chamber, a study of investigating for relationship between NO_x emissions and non-homogeneity distribution of methane-air mixture was conducted. Non-homogeneity distribution was generated by varying the period after fuel injection and movement of perforated plate. Non-homogeneity distribution was measured by the acetone planar LIF technique and the heterogeneity index was determined. The exeriments were performed under high pressure and temperature conditions in the chamber. The effects of heterogeneity index and initial condition in the chamber on NO_x and conbustion efficiency were studied in detail. The trend of NO_x and combustion efficiency was varied in different heterogeneity mixture at the same excess air ratio.
