This final project performed the optimization of reverse combustion chamber design of 500 N turbojet engine static thrust by using a 2D axisymmetric CFD method. Optimization of reverse combustion chamber design done because the first generation 500 N turbojet engine that has been manufactured and tested indicate problems in the combustion chamber, i.e. combustion didn’t occurs in the combustion chamber primary and secondary zone, but reach by the exhaust nozzle of the engine. <br /> <br /> <br /> <br /> <br /> The CFD software that used at this final project is FLUENT 6.3.26. The geometry and meshing of each reverse combustion chamber design was created by using GAMBIT 2.3.16 software. <br /> <br /> <br /> <br /> <br /> The analysis of each reverse combustion chamber design modification is done by observing the phenomenon that occurs in each design. The next stage is done by investigating the performance parameters of each modified reverse combustion chamber design. The investigated performance parameters are the uniformity of temperature at the combustion chamber outlet, the average temperature at the combustion chamber outlet, total pressure losses, and the Pattern Factor (PF). <br /> <br /> <br /> <br /> <br /> Most of the analysis presented here is of qualitative descriptions of the flow and combustion phenomena that occurs. Explanation of the performance parameters of each design is supported and completed by tables and comparison charts of each reverse combustion chamber design modifications. <br /> <br /> <br /> <br /> <br /> At the end of this final project report, the best design of the reverse combustion chamber between the existing designs is determined. The determination of the best design is only based on the flow characteristic analysis of the CFD simulation results, and the performance parameters of each reverse combustion chamber design.
