| Outline of Final Research Achievements |
The purpose of this study was to develop a numerical method to investigate the influence of multi-physics phenomena such as erosion and icing occurring at the jet engine component on the entire jet engine system.
From FY2016 to FY2017, research activity focused on the development of analysis programs. Numerical simulations coupled with cycle analysis and Multi-physics CFD using the developed analysis was performed in FY2018.
The numerical method was successfully developed. Although it became clear from the research that the computational load of the developed coupling method is higher than initially assumed, in future research, solve the highlighted issues will be solved.
