Film Cooled Small Turbine Blade Research. Volume I. Aerodynamic Study of Secondary Flows.
Abstract
The overall study concerns an investigation on the cooling and aerodynamic problems associated with a high speed turbine cascade of small blade height for use on small gas turbines. The secondary flow behavior in turbines is presented in Vol. I and the cooling aspects are presented in Vol. II. Vol. I reports on the study of small aspect ratio blades. A program has been initiated with the aim of obtaining a better physical understanding of the real secondary flow phenomenon. The total program will cover a period of three years. It includes very detailed low speed tests with measurements inside the blade passage, cross checking of the low speed tests in a high speed cascade and the investigation of the effect of film cooling on secondary flows. Vol I, which reports on the first year efforts, presentes mainly low speed test results and a limited amount of high speed data.
