Der Einfluss peridisch instationaerer Zustroemung auf das Transitionsverhalten von Verdichtergittern (The Influence of Periodically Non-Stationary Afflux on Transition Behavior of Compressor Grids)

Abstract

The primary goal of this study is to obtain a deeper look into the physical occurrences within the shovel border layer. The author accomplishes this effort through a detailed examination of non-stationary flow behavior of compressor shovels with Controlled Diffusion Airfoil (CDA)-profiling under the influence of after-running depressions of current salient shovel rows. In addition to the checking of the precision of stationary and non-stationary calculatory processes, criteria are defined for the layout of modem compression shovels under the rubric of rotor/stator interaction. An overview of the literature is then given regarding both the basic principles of non-stationary transition behavior under the influence of after-running depressions as well as the most up-to-date scholarship on the problematics of the field discussed.
