Rugalmas szalagok, mint aktív turbulenciagenerátorok laboratóriumi vizsgálata

Abstract

This paper deals with the construction and the measurements of a novel type turbulence generator which contains vibrating elastic tapes as active elements to increase the turbulent intensity of the main flow. It explains the basic physical phenomena of the vibrating tapes and the build process. Furthermore the results of the measurements are presented, too. Since the device was assembled in a wind tunnel constructed for investigation of turbulence generators, thus it was possible to investigate the effects on the fluidic properties of the main flow. CTA measurement technique was applied due to its beneficial properties.
