Abstract
In order to reduce the cost of mesh genration and achieve practical accuracy, HINOCA-AE, a thermal and fluid dynamics solver with the Cartesian grid, is now being developed. The purpose of this research is to expand the application of numerical analysis for aero engine combustor design.

Achievements of the Year
In order to verify whether a solver based on the Cartesian grid and the Immersed boundary method can be used to analyze the flow with practical accuracy, a flow analysis was conducted on a test combustor under non-combustion and combustion conditions. Although there are some issues, such as improving the conservation, it was confirmed that the analysis can be performed with practical accuracy.
