Burner Fluent simulation issues
Thread Content
Most burners have air inlets located on the sides, but in order to simplify the model and reduce the number of grid elements, many people simply place the air inlet boundary and the fuel inlet boundary at the bottom of the burner. Such a result must be quite far from the actual value, right? After conducting simulation calculations based on the actual model, I found that when the air inlet boundary is placed on the side, it is difficult for the results to converge, and the radial distribution of air within the furnace is highly uneven. Since the burner operates with natural ventilation, it is easy to understand why there is more air on the side where the air inlet is located. If the air inlet boundary is set at the bottom of the burner and the air volume remains constant, the simulation process converges easily. But, are such simulation results of any reference value? ? Anyone who has done Fluent simulations for burners, please help clarify this. Thank you! !
Thank you, this question has been bothering me. . .
