PECULIARITIES OF FLOW AND MIXTURE FORMATION IN MICROIET BURNER DEVICES WITH ASYMMETRIC FUEL DISTRIBUTION
The purpose of the work is to establish the regularities of the isothermal flow and the mixture formation of the fuel gas and oxidant in the microjet burner devices with an asymmetric fuel supply. The main tasks of the work are the analysis of the effects of the influence of the value of excess air factor on the flow structure and the features of the mixing of fuel and oxidant. As a method of research, the CFD modeling method using the FLUENT code was used. According to the results of the studies carried out in the relatively wide limits of the change in the excess air factor (1.5 ≤ α ≤ 4.0), the regularities of the effect of the value of this factor on such flow characteristics in the burners studied as the length of the reverse current zone behind the flame stabilizer, which is responsible for the combustion stability, the location of main vortex in this zone, the values of the mean-square velocity pulsations, and so on. The features of the mixture formation in the variation of the α value in the burner devices under investigation are revealed. The dependence on the mean α of the methane concentration in the reciprocal zone is established and given its interpretation, taking into account a number of competing factors.
