Available in PDF, EPUB and Kindle. Book excerpt: This experimental investigation involved the study of gas film cooling from a single row of spanwise angled holes using the stagnation region of a cylinder in cross flow to model the leading edge of a turbine vane. The objective was to obtain data for the local convective heat transfer rates to a highly cooled, curved surface exposed to a turbulent hot mainstream flow and a secondary, film coolant flow. Since the leading edge of the first stage, inlet turbine vane experiences some of the most severe thermal loads found in the turbine engine, effective film cooling is most important in this area. Film cooling of the leading edge area was modeled by making heat transfer measurements on the front stagnation region of a cylinder in cross flow. Experiments were conducted in a rectangular duct using a film cooled cylindrical test surface normal to a two-dimensional freestream flow. A gas turbine combustor provided heated air flow to simulate a Reynolds number typical of a high pressure, high temperature turbine vane. Internal convection cooling of the cylinder allowed a gas-to-wall temperature ratio of 2.1 to be achieved while using a moderate freestream gas temperature (1000R; 555K. The film coolant was chilled to obtain a coolant-to-freestream density ratio of 2.2, representative of the gas turbine environment. The cylindrical test surface was instrumented with miniature heat flux gages, and wall thermocouples to determine the influence of the film coolant blowing ratio and the injection hole geometry on the film cooling performance.

This book was released on 1982 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analysis and computational procedure have been developed for predicting flow and heat transfer which results from coolant injection through a single row of round holes oriented at an angle to a flat surface with the injection and free stream velocity vectors coplanar. This method solves the compressible Navier-Stokes equations and utilizes zone embedding, surface-oriented coordinates, interactive boundary conditions, and an efficient split LBI scheme. The approach treats the near-hole flow region where the film cooling flow is initially established. Prior studies considered only laminar flow in order to simplify development of the computational procedure. Under the present effort, several turbulence models suitable for the discrete hole film cooling problem have been investigated by predicting a number of test cases from the 1980-81 AFOSR-HTTM Stanford Conference on Complex Turbulent Flows. The calculation of a discrete hole film cooling case for an injection angle of 35 degrees has been initiated using a mixing length turbulence model. These results will be compared with the experimental data of Kadotani and Goldstein, a recalculation with either a turbulence kinetic energy/algebraic length scale or a turbulence kinetic energy/warranted by the data comparison.
