A Comparison of Two Combustor Modeling Approaches for Real Time Turbofan Engine Model

摘要：

This paper presents two combustor modeling approaches for real time turbofan engine model. The two approaches are called Integral Approach and Hybrid Approach. Integral Approach resorts to the effect of mass and energy storage in a volume to establish the pressure and temperature differential equations. Whereas Hybrid Approach considers only the effect of mass storage in a volume to achieve pressure differential equation, and the temperature is solved through a local iterative. Furthermore, simulation is carried out on both set-point and transient conditions. The results show both the two models fairly well match the experiment data. Ultimately, comparisons of the two models in terms of their efficiency and precision are presented.
