TL;DR: In this article, the authors compared the performance of the standard k-e model, the Shear Stress Transport (SST) k-ω model and the Reynolds Stress Model (RSM) model on a perforated panel diffuser with lobed orifices.

TL;DR: In this paper, a numerical study was carried out to investigate the effects of diffuser flange inclination angle (φ) and diffuser depth inside the exit of the diffuser (hi/Drotor) on the wind-lens turbine system performance.

TL;DR: In this article, a multi-stage diffuser nozzle for use as a drill bit nozzle jet includes a flow restriction portion upstream of a fluidic distributor portion, and also preferably includes a transition region between these two.
Abstract: A multi-stage diffuser nozzle for use as a drill bit nozzle jet includes a flow restriction portion upstream of a fluidic distributor portion, and also preferably includes a transition region between these two. The flow restrictor communicates with the interior fluid plenum of a drill bit and is used to limit or restrict the total flow of drilling fluid by having a relatively small cross-sectional area for fluid flow. The fluidic distributor communicates with the flow restrictor and reduces the exit flow velocities of the drilling fluid as the drilling fluid is ejected from the nozzle by providing a relatively larger cross-sectional area for fluid flow. The fluidic distributor also directs the flow paths of the drilling fluid to locations such as cone surfaces that are prone to bit balling. The transition region is an area that dampens fluid pressure oscillations in the drilling fluid.

25 Apr 1994TL;DR: In this paper, the authors describe a vaned diffuser consisting of a pair of diffuser plates and a plurality of guide vanes arranged between them in a circular cascade manner, where the vanes are equal in leading-edge radius to each other, but are different in length from each other.
Abstract: A centrifugal compressor comprises a centrifugal impeller and a vaned diffuser. The diffuser includes a pair of diffuser plates and a plurality of guide vanes arranged between the pair of diffuser plates in a circular cascade manner. The guide vanes are equal in leading-edge radius to each other, but are different in length from each other. At least one short guide vane is arranged between the adjacent long guide vanes. The total number of the guide vanes is more than the number of blades of the impeller. A throat is formed on one but not the other of flow passages between the guide vanes.
