EXPERIMENTAL STUDY ON FIBER SUSPENSIONS IN A CURVED EXPANSION DUCT WITH PARTICLE IMAGE VELOCIMETRY

Abstract

The visualization measurement of internal flow field in a curved expansion duct s experimentally studied using particle image velocimetry technology and the influence f flow rate on flow field is analyzed. The streamline distribution and related erformance curve in the internal flow field can be figured out through further nalysis of experiment data. The results show that fiber orientation is mainly ffected by velocity gradient, the fibers near the wall are aligned with the flow direction ore quickly than the fibers in intermediate region, and the fibers near he concave wall are more quickly aligned with the flow direction than the convex all. The larger inlet flow rate which will accordingly lead to increase inlet velocity nables the more quick adaptation and steady of fibers in flow direction.
