Flow Visualization in Two Intersecting Ducts

Flow Behavior

Abstract

Three kinds of experiments are conducted to determine the mechanics of flow inside two intersecting square ducts : flow visualization by means of dye injection, velocity measurement using laser Doppler anemometry, and pressure measurement using a piezometer. The geometrical dividing line in the intersection zone of the two ducts forms a flow divider separating the flow network into two independent, symmetrical flow units. The flow characteristics on the flow divider and in the intersecting section are disclosed.
