Abstract: This paper describes a program of research in which, by using laser-Doppler anemometry, the variations of artificially induced flow perturbations to represent turbulence in an engine have been ...

Abstract: This paper describes a continuing experimental program in which the frequency and amplitude of turbulence in the mainstream flow over a cascade of turbine blades are separately and controllably ...

Abstract: This paper describes an experimental study of an air-cooled gas turbine disk using the model of a disk rotating near a shrouded stator. Measurements of pressure distribution, frictional moment, ...

Abstract: A relatively simple theory is presented that can be used to model the flow and pressure distribution in a brush seal matrix. The model assumes laminar, compressible, isothermal flow and requires ...

Abstract: This paper describes a program of experimental and analytical research designed to evaluate the aerodynamic and thermodynamic performance of transpiration-cooled porous surfaces in the high-temperature ...
