An investigation of the flow in turbojet test cells and augmenters

A two-dimensional elliptic computer model was adapted to the solution of the flow field in a turbojet thest cell section which contained the engine exhaust duct and augmenter tube. Various engine power settings, augmentation ratios, and augmenter geometries were investigated. Flow visualization and static pressure recovery were primary objectives subject to specified engine power settings and augmentation ratios. Capabilities and limitations of the model are discussed.
