Finally the flow turns to exit through the two transfer tubes. The flow boundaries are depicted as transparent, glassy looking structures to aid viewer orientation. The ribbons themselves show the direction and orientation of the flow. Colors indicate starting location. The computational\ fluid dynamics codes were developed by a joint NASA/ AMES Research Center and Rocketdyne team. The CFO study of the HGM was conducted by James L.C.
