Smooth setting of ammonia combustion

1. First, choose the appropriate reaction mechanism. The reaction mechanism of ammonia combustion can adopt GRI-Mech reaction mechanism, which contains a large number of chemical reactions of ammonia combustion and can accurately describe the characteristics of ammonia combustion. Set gaseous reactants and reaction products. In Fluent, in order to simulate the combustion of ammonia, it is necessary to select the correct gaseous reactants and reaction products. For the combustion reaction of ammonia, the reactants are ammonia and oxygen, and the reaction products are nitrogen, water vapor and carbon monoxide. Define the reaction according to the requirements and conditions of combustion.

2. Secondly, to configure chemical reactions, it is necessary to configure chemical reactions in Fluent in order to correctly apply the reaction mechanism to the simulation. You can select the "Chemical Reaction" option under the "Simulation" menu bar in Fluent to configure it. Select the appropriate physical model. In Fluent, it is necessary to choose a suitable physical model to simulate the heat and mass transfer of ammonia in the combustion process. For the combustion process, it is necessary to choose a suitable component transport and combustion model.

3. Finally, set the boundary conditions. In Fluent, it is necessary to set appropriate boundary conditions to correctly describe the combustion area, gas flow and gas composition. Parameters such as gas velocity, pressure, temperature, composition, reaction and mass transfer need to be set.
