Design of Annular Combustion Chamber for a Micro Turbofan Engine

The design of an annular combustion chamber for a micro turbofan engine is emphasized in the present work. The combustion chamber is designed using biogas as a fuel. The design principle is based on the constant pressure, enthalpy addition process. The dimensions of the combustor are calculated based on different empirical formulae. The air mass flow is then passed round across the zones of the combustor. The cooling specification is met using the cooling holes. The whole combustion chamber is modelled using suitable modelling software. The model is analyzed using various parameters at various stages and levels to determine the desired design. The aerodynamic flow characteristics are numerically simulated by means of the analysis software. The air-fuel mass ratio, combustion turbulence, the thermal and adequate cooling analysis is carried out. The expected outcome is presented in image outputs and graphs.
