Design, Fabrication and Instrumentation of an Annular Diffuser Research Facility.

Abstract

Annular diffuser and annular diffuser inlet velocity profile data is required to verify theoretical annular diffuser velocity profile prediction techniques. This document records the advancements made during the second phase of an effort to fabricate and instrument an Annular Diffuser Research Facility. A laser doppler velocimeter, which is the primary component of instrumentation, was assembled and proper operation was verified. A stilling chamber was fabricated to provide uniform, non-separated flow at the entrance to the preexisting annular test section components. Velocity profile data was collected and analyzed and repeatability was demonstrated at four axial stations within the annular diffuser and annular diffuser inlet test sections. (Author)
