Abstract: Combustion of fuel with oxidizer provides continuous power for the vehicles to move forward. Well-designed combustor produces complete combustion, where water and carbon dioxide are the stable products. Incomplete combustion additionally produces more emission in the form of carbon monoxide and nitrogen oxides due to factors like poor mixing of the air and fuel or insufficient excess air. Therefore in order to understand the importance of various parameters which affects the combustor performance and to design the effective combustor, which delivers high combustion efficiency, it is very essential to study the combustor using CFD techniques, performed using ANSYS Fluent software. Computational or CFD methodology is used here to perform combustion simulation on the typical combustor models, where hydrocarbon like kerosene (Jet fuel) is burned with incoming air at high velocity. Computational models are created with pre-processor such as Gambit and subsequent processing and post processing with Ansys Fluent as the software. Suitable turbulent model, chemical model and physical models are enabled to analyse and plot the mass fraction of various chemical species along the length of the combustor. Fuel Additives are used to evaluate the peak temperature. The combustion efficiency of this hydrocarbon combustion is evaluated using this numerical tool.
