Abstract

This paper describes the relation between bend diffuser characteristics and internal flow. Diffusers were bent into U and snake shapes within the limitation of a single plane. In these experiments, area ratio, divergent angle and curvature radius ratio of bend elements were varied. Five types of inlet velocity profiles also were used, and their effects on diffuser performance and internal flow were investigated in detail. The following is a report on the fruitful and interesting results we have obtained.
