Apr 1, 2021 · The cylinder cross-sectional aspect ratio AR (length-to-width) is varied as 0.25, 0.5, 1.0, 2.0, 3.0 and 4.0. The focus is given on how AR and Re influence the flow structure and associated aerodynamic parameters.

Apr 26, 2006 · Reynolds numbers from about 50 to 4 × 10 4 were investigated. Different aspect ratios, at low blockage ratios, were achieved by varying the distance between circular end plates (end plate diameter ratios between 10 and 30).

Nov 7, 2023 · Here, we will consider two aspect ratios for the cylinder: AR = h/d = 1:2 and 2:1, where d is the width and h is the height of the cylinder. Specifically, AR = 1:2 indicates that the width of the cylinder is double its height, while AR = 2:1 …

Jun 14, 2019 · DNV provides guidance on the aspect ratio effect on the drag coefficient of a cylinder, for which no experimental source data has been cited. The DNV design guidance has wide usage in the...

While the literature on small aspect ratio cylinders in normal ow is sparse, there exists even less information at other orientations. Hoerner8 compiled data for cylinders and disks in axial ow (with the at face normal to the ow).

Jun 6, 2023 · In order to better understand the combined impact of aspect ratio and Reynolds number a series of wind tunnel tests and numerical simulations has been conducted for cylinders with two free ends having aspect ratios of 2–15.

Apr 1, 2015 · Most publications on this subject refer to flow around surface-mounted low aspect ratio cylinders, in that the three-dimensional structures formed behind the cylinder significantly change the wake downstream and consequently modify …

Apr 5, 2015 · The aspect ratio can easily be defined for rectangular geometries ($AR = height/width$). Is there a definition for aspect ratio of a dome, cylinder, and pyramid (Here standard pyramid and dome were meant; like a square right pyramid and a semi-circular dome)?

Oct 1, 2024 · Time-resolved PIV system was used to investigate the effects of streamwise aspect ratio on flow characteristics of free surface-mounted rectangular cylinders of aspect ratios, AR1, AR2, AR2.5, AR3, AR4, AR5, and AR8 at a Reynolds number of 11100.

Finite-span circular cylinders with two different aspect ratios, placed in a cross-flow, are investigated experimentally at a cylinder Reynolds number of 46,000. Simultaneous measurements of the flow-induced unsteady forces on the cylinders and the stream velocity in the wake are carried out.
