Abstract
Flow visualization was numerically carried out for some internal flowfields. The configurations dealt with in this simulation include high bypass fan blade rows and a circular cross sectioned S-duct with two circular arc bends. These flowfields were first analyzed by viscous flow solvers, and then visualized by simulating surface oilflow patterns, streamlines, etc. The flow visualizing programs were developed in National Aerospace Laboratory in order to represent the results of three-dimensional numerical flow analyses. Additionally, these phenomena were much more clearly visualized with the assistance of animation techniques.
