ANALYSIS OF ASYMMETRIC FLUID FLOWS BY LDA

摘要

This paper is the continuation of the fluid flow investigation by laser Doppler anemometry (LDA) represented on LASER '95. The investigation is focused on tubes of complex shape. In those cases mathematical and even numerical treatments may be very difficult and time consuming. Some asymmetrical flows in glass tubes (in which flow velocity lines are not symmetrical) are investigated - 1. asymmetrical ramification of the flow and -2. flow in one sided spherical expanding of the cylindrical tube. With the respect of ray tracing and scattering, optimal configurations of installations were determined, and corresponding measurement results processing were performed. Finally obtained results are presented in various chart and picture forms in order to expose the most comprehensive image of the analyzed flow fields.
