Investigations Regarding the Drag Characteristics of Flow-Disturbing Bodies Which Are Arranged in Line and Attached to the Wall.

摘要

The flow characteristics of rectangular bodies mounted on the base area of a rectangular closed wind tunnel are investigated. As many as four bodies are mounted in line with equal distances between successive bodies. The Mach number of the flowing air is in the range from 0.1 to 0.5. Total and individual drag values could be charged within a wide range by a suitable selection of the distance between successive bodies.
