TL;DR: In this paper, three vaneless diffuser designs, varying in diffuser width and tip clearance, were studied experimentally for a centrifugal compressor with three different diffusers, and the results showed that the compressor overcomes the effect of the diffuser length.
Abstract: Three vaneless diffuser designs, varying in diffuser width, for centrifugal compressor were studied experimentally. Along with the diffuser width, the tip clearance was altered. The compressor over...

TL;DR: In this paper, the influence of the diffuser inlet shape on the performance of diffuser and the whole compressor stage was investigated using a single-stage centrifugal compressor and three different vaned diffusers.
Abstract: Results from an experimental study of the influence of the diffuser inlet shape on the performance of the diffuser and the whole compressor stage are presented The investigations were carried out using a single stage centrifugal compressor Three different vaned diffusers were tested From detailed flow field measurements the influence of the diffuser inlet shape on the performance of the essential components of the compressor stage, ie the impeller, the diffuser, and the collecting chamber was analyzed It is shown that the reaction of the vaned diffuser on the efficiency of the impeller is only weak but the losses in the collecting chamber are considerably affected by the used diffuser typesCopyright © 1983 by ASME

TL;DR: In this paper, a diffuser is provided in an illumination system, where the diffuser can be capable of blocking significant amounts of ultraviolet (UV) radiation by using a glass substrate which supports a UV coating.
Abstract: A diffuser is provided in an illumination system, where the diffuser is capable of blocking significant amounts of ultraviolet (UV) radiation. In certain example embodiments of this invention, the diffuser includes a glass substrate which supports a UV coating(s) that blocks significant amounts of UV radiation thereby reducing the amount of UV radiation which can makes its way through the diffuser. In certain example embodiments, the coating may including particulate so that the coating may both diffuse visible light and perform UV blocking.
