LDA, Classical Probes and Flow Visualization in Experimental Investigation of Turbulent Swirl Flow
Апстракт
Investigation of turbulent swirl flow occupies attention of many researchers as it has great significance on processes in nature, engineering applications, medicine and elsewhere. Here are presented experimental results of research of turbulent swirl flow generated on the axial fan pressure side. These results are obtained with Laser Doppler Anemometry (LDA), classical probes with precise micro-manometers and flow visualization with usage of Nd:Yag laser in circular pipe for Reynolds number 1.5•10^5. Flow integral characteristics obtained from LDA results have shown good agreement with ones calculated on the basis of classical probe measurements, except in the central region, where radial, the third velocity component, is present. Flow visualization reveals vortex dynamics.
