Unsteady aerodynamic response characteristics of gas turbine fuel injectors
thesis
posted on 2017-05-19, 08:27 authored by Jialin SuFor medium and large gas turbine engines, the lean combustion technology has been recognised as one of the effective solutions for emission reduction. However, such systems are often susceptible to thermo-acoustic instability. As an essential component of the combustion system, the fuel injector plays a critical role in the feedback loop that leads to this instability. This thesis presents a study on the unsteady aerodynamic response of generic lean burn injector passages to incident acoustic waves. Single and two passage injector configurations were considered which consist of many of the representative features comprising a modern lean burn fuel injector. [Continues.]
