Abstract

FaSTAR-Move, an extended version of the fast unstructured-grid flow solver FaSTAR, is developed to analyse flow field around moving/deforming objects such as external store separation, flutter, rotor, and compressor/turbine of aero-engines.

Reasons for using JSS2

JSS is necessary to complete numerical simulations of unsteady phenomena and to understand it in short time span.

Achievements of the Year

FaSTAR-Move was extended to enable analysis for aero-engine blades and helicopter rotor blades. It was comfirmed that FaSTAR-Move can reasonably simulate the flow field around them.
