Download or read book Endwall Heat Transfer Measurements in a Transonic Turbine Cascade written by and published by . This book was released on 1996 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Turbine blade endwall heat transfer measurements are given for a range of Reynolds and Mach numbers. Data were obtained for Reynolds numbers based on inlet conditions of 0.5 and 1.0 x 10(exp 6), for isentropic exit Mach numbers of 1.0 and 1.3, and for freestream turbulence intensities of 0.25% and 7.0%. Tests were conducted in a linear cascade at the NASA Lewis Transonic Turbine Blade Cascade Facility. The test article was a turbine rotor with 136 deg of turning and an axial chord of 12.7 cm. The large scale allowed for very detailed measurements of both flow field and surface phenomena. The intent of the work is to provide benchmark quality data for CFD code and model verification. The flow field in the cascade is highly three-dimensional as a result of thick boundary layers at the test section inlet. Endwall heat transfer data were obtained using a steady-state liquid crystal technique.

Download or read book Detailed Boundary Layer Measurements on a Transonic Turbine Cascade written by D. J. Mee and published by . This book was released on 1990 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The boundary layers of a transonic turbine blade have been measured in detail. The full velocity profiles have been measured at a number of stations on both the suction and pressure surfaces, at conditions representative of engine operation, using a Pilot traverse technique and a large-scale (300 mm chord) linear cascade. This information has made it possible to follow the development of the boundary layers, initially laminar, through a region of natural transition to a fully developed turbulent layer. Comparisons with other, less detailed, measurements on the same profile using Pilot traverse and surface-mounted thin films confirm the essential features of the boundary layers.

Download or read book Analysis of the Effects of Wake Passage on Heat Transfer in a Linear Turbine Cascade written by and published by . This book was released on 1993 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study investigated the effect of wake passage On the heat transfer in a linear turbine cascade. The apparatus used was the Air-Force Institute of Technology linear Turbine Cascade Test Facility (TCTF). The TCTF was fitted with a be Pulley system to facilitate a series of translating bars. The bars, when passed d upstream of the cascade, created a series of wakes. The parameters varied were freestream model Reynolds number and bar conditions, i.e., bars in, bars out, and bar passing frequency. One blade in the TCTF was instrumented to allow pressure and temperature measurements at discrete points on the blade's surface. From the pressure and temperature data the convective heat transfer coefficient at these discrete locations was calculated. Results were compared to previous TCTF heat transfer data, empirical solutions, and other wake passage experiments. For all tests with closely spaced bars, the effect of wake passing on the heat transfer of the blade was similar to the effect of grid-generated 10% freestream turbulence on the cascade.

Download or read book A Frequency Domain Analysis of Surface Heat Transfer/Free-Stream Turbulence Interactions in a Transonic Turbine Cascade written by David G. Holmberg and published by . This book was released on 1996 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The relationship of time resolved surface heat flux to the turbulent free stream flow over a turbine blade is investigated. Measurements are made in a transonic linear cascade with a modern high pressure turbine blade profile. Time resolved direct heat transfer measurements are made with Heat Flux Microsensor (HFM) inserts along the pressure side, and with one HFM directly deposited on the suction surface near the leading edge. Simultaneous velocity measurements are made above the heat flux sensors using miniature hot wire probes. Grids are used to produce two turbulence fields of constant inlet turbulence intensity, Tu=5%, but significantly different integral length scales (Ax). Results are compared with a low free stream turbulence baseline condition. Special emphasis is given to frequency domain analysis of the data via coherence function magnitude and phase, energy spectra, and time auto and cross correlations.

Download or read book Unsteady Aerodynamic and Heat Transfer Studies in a Highly-Loaded Transonic Turbine Rotor Cascade with Simulated Shock/Wake Passing written by and published by . This book was released on 1996 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of the research effort is to integrate fluid and heat transfer studies in a heated transonic turbine cascade in order to develop a better understanding of the complex flow physics involved in the coupling of the fluid flow and heat transfer phenomena in an unsteady flowfield. To that end detailed, time resolved aerodynamic and heat transfer measurements are taken in the experiments. Unsteady passing shock is generated in a shock tube and introduced into the test section of the cascade to simulate the shock wave passage similar to an actual turbine environment.
