Simulation and analysis of turbulent flame and its effect on the wall of aero engine combustor

The main objective of this study is to simulate the behavior of the reactive flow of the turbulent flame in aeronautical combustion chamber of the ALLISON-T56 turboprop, and contribute to the analysis of flame structure and determine for given pressure and temperature of fresh gas the behavior of the thermodynamic parameters of combustion. The numerical approach is based on the resolution of basic equations of turbulent combustion using Ansys-Fluent code where the turbulence model K-e is chosen, the geometry of the combustion chamber is made using Ansys-workbench software. Thereafter, we simulate the transient temperature field through the wall of a tubular combustion chamber, and the characterization of the thermal expansion, the thermoelastic stresses and strains with the physical properties of refractory materials. The obtained results are then compared with the results of the scientific literature
