Flow Visualization in Two Intersecting Ducts

Characteristics of Momentum within Intersecting Zone

Abstract

Experiments are performed to investigate flow characteristics in intersecting ducys by means of particle-suspension flow visualization, laser Doppler velocimetry, and piezometry. The intersecting angle and the Reynolds number are varied. The flow characteristics on the flow divider and in the intersecting zone are disclosed. Other important disclosures include the occurrence of ramming phenomena in the intersecting section, and the existence of an "energy supply point"(with maximum velocity and minimum pressure) on the flow divider.
