CONCEPTUAL AND THEORETICAL DESIGN MODELLING AND SIMULATION ANALYSIS OF A TURBOFAN ENGINE AT OPTIMAL PERFORMANCE

In the current study, a novel design of a turbofan engine was theoretically conceptualized, model and simulated for optimal performance during operation. This was achieved byusing Autodesk Inventor software and Autodesk CFD software. The study also employed the tool of finite element analysis in modelling performance safety during optimal operation. A new turbofan engine was designed by making use of proper tolerance analysis and performance check in the system design of the turbofan engine. Due to this, several fundamental numerical analysis and simulation was done on blades and geometries in order to optimize the system performance at better efficiency during operation at dif ferent cycles of fluid properties and flow station. To achieve this, the different components of the system aerodynamic design parameters, the sizing of the system component and the system efficiency were computed and simulated by using the tool of CFD and taken into consideration many aspects of the turbomachinery operating components that were modelled at optimal and satisfactory performance. A compressive design and analysis of a turbofan engine was revealed. It was also shown that, the energy content of the design system increased significantly due to varying parameters for material selection in the design system. It was also shown that material selection plays a vital role on performance, manufacturing cost and the system life cycle and efficiency during operation. Varying modelling and design analysis of fan, compressors, combustor, turbines, and nozzle were revealed by Autodesk Inventor software and Autodesk CFD software significantly impact design performance during operation. It was also revealed tha t a numerical analysis of the system mass flow rate on blades and inlet geometries impacts the performance of the turbofan engine and the system became more efficient during operation.
