Thermophysics and Thermal Power Engineering| Summary: | The objective of the work is to establish the regularities of the flow of a single gas in micro-jet burner devices with a three-row fuel supply system. The burner devices under consideration are intended for operation under conditions of variable values of the total excess air coefficient, 1.1 ... 1.5. The objective of the study was to determine the effects of the influence of the row number of gas supply holes on various characteristics of the non-isothermal flow in the proposed burners. CFD modeling based on the DES approach was used as a research method.
Based on the results of the comparative analysis of the flow characteristics when feeding fuel gas to different rows of gas supply holes, it is shown that these characteristics can significantly depend on the row number of the fuel supply. It was found that with an increase in the row number, the indicators of the recirculation zone behind the flame stabilizer change significantly. The levels of flow rates, velocity pulsations, etc.
The research results can be used in the design of micro-flare burners of the stabilizer type. |
