Abstract

The design of the fuel injector is one of the important operating factors that determine the extent of mixing of air and fuel in an MEMS gas turbine engine. In this study, we consider a system with three inlet ports with each port having multiple injectors. We perform a parametric study by varying the arrangement of fuel injectors and difference of ratio of fuel supply. The results are presented in terms of the premixed flow distribution and equivalence ratio.

MEMS 가스터빈 엔진에서 연료와 공기의 혼합에 영향을 미치는 중요한 요소중 하나는 연료 분사구 형상의 설계이다. 본 연구에서는 3 개의 연료 주입부와 각 주입부에 연결된 여러 개의 분사구에 의해 연료와 공기가 혼합되는 시스템을 고려하여 분사구의 배열과 연료 공급비율의 변화에 따른 혼합 정도를 당량비를 통하여 정량적으로 해석하였다.
