Untersuchungen zur Optimiening der Kueh11uft-Ausblasekonfiguration fortschrittlicher Turbinenbeschaufelungen (Experiments on the Optimization of Cool Air Blow-Off Configurations of Advanced Turbine Blades ).

摘要

Deftly building upon a strong literature on film cooling in aerodynamics, the author observes various film cooling configurations in experiments designed to provide a better understanding of the TRACE-S and FINE/ Turbo instruments. The goal is then to put forward the optimal blow-off configurations for the turbine blades under scrutiny. It is claimed that this study differs from its numerous forerunners in that it takes into account not only the standard aerodynamic measurements, but also information on the distribution of heat transfer coefficients on the sucking side of a film-cooled, evenly-keeled turbo grate within the maintenance of the most important similarity parameters.
