Abstract
Unstructured-grid flow solver FaSTAR-Move and grid generator BOXFUN are applied to aero-engine elements with complicated configuration (such as linear and rotating cascades). Through the calculation, these programs are tested and investigated for the deficiency and future issue for improvement of accuracy.

Reasons for using JSS2
Aiming to do large scale calculation in the future, programs should be tested under the same computational environment.
Achievements of the Year
Steady Reynolds averaged Navier-Stokes (RANS) calculations were performed for the transonic compressor, Rotor 67 and the cooled turbine cascade, T106A using FaSTAR-Move. The converged solutions has been obtained and validated.
