Summary

An analysis for the flow deflection characteristics of wire gauzes is shown to provide agreement with and a correlation for the existing experimental results. These characteristics are used to control the flow in a very short diffuser, with a high expansion ratio in which the flow diffuses across oblique gauzes in the form of a pyramid. This design is shown to give satisfactory results for flow uniformity at outlet, degree of pressure loss, and steadiness of flow.

Übersicht

Die Eigenschaften der Strömungsablenkung durch Drahtgitter werden analysiert und es wird gezeigt, daß die Ergebnisse mit den bisher bekannt gewordenen Experimenten übereinstimmen. Die Ergebnisse werden auf die Strömung in einem sehr kurzen Diffuser mit hohem Expansions-Verhältnis angewandt, in dem die Strömung längs eines schrägen, pyramidenförmigen Drahtgitters expandiert. Es zeigt sich, daß diese Anordnung zufriedenstellende Ergebnisse bezüglich gleichförmiger Strömung am Ausgang, Druckabfall und Konstanz der Strömung ergibt.
