Reasons for using JSS2
The reason for using JSS2 is to accelerate the RANS simulation on relatively large computational grids to enhance research activites.
Achievements of the Year
We conducted RANS simulations of the S-shape duct which is one of the benchmark problem of AIAA Propulsion Aerodynamics Workshop (PAW). We compared the numerical results (TPR, DPCP) obtained by FaSTAR and other CFD results from PAW and comfirmed that FaSTAR could be applied to the simulation of internal flow.
