Influence of height of plate flow turbulizers on flow characteristics in microflow burners

The use of flow turbulators in microflame burners is intended to intensify heat and mass transfer processes in the active combustion zone and, in general, to improve the energy and environmental performance of burners of this type. The available studies of various methods of intensifying combustion processes do not cover many issues related to the regularities of the influence of various factors on the characteristics of the working processes of microflame burners in the case of using one or another method of intensifying combustion. It is important to establish the dependence of these characteristics on various design parameters of the flow turbulators. The purpose of this study is to establish the patterns of influence on the flow characteristics of the height of the turbulizing plates located on the side surfaces of the flame stabilizers. The research was carried out on the basis of computer simulation using the FLUENT code. The results of the studies performed showed that with an increase in the height of the turbulizing plate from 0.005 to 0.01 m, there is a significant change in the flow pattern, which manifests itself in the lengthening of the circulation flow zones behind the flame stabilizer, in an increase in the maximum absolute value of the velocity in these zones, an increase in the level of velocity pulsations. and the size of the subregions in which these pulsations are significant, etc. Prospects for further research are related to the study of the considered situations in the conditions of reacting flows.
