Abstract
In this project, we will apply next-generation acoustic liner to combustor. To perform the numerical analysis of combustor with the acoustic liner by using HINOCA-AE which is CFD solver for aircraft engine combustors.

Reasons and benefits of using JAXA Supercomputer System
We have designed the combustor by using the carbon neutral fuel (ex. hydrogen). To differ from the flow field of jet fuel, we need to investigate the flow field of carbon neutral fuel on the design phase.
Achievements of the Year
Our numerical analysis is focused on the flow field of the inner combustion chamber by using carbon neutral fuel. Large Eddy Simulation (LES) was performed with the inner combustion chamber as shown in Fig.1 The time-averaged temperature field are shown in Fig.2.According to numerical analysis, we obtained results of the flow field around injector, the dilution holes and so on.
