• W2808240116 abstract "A group of three multiscale inhomogeneous grids have been tested to generate different types of turbulent shear flows with different mean shear rate and turbulence intensity profiles. Cross hot-wire measurements were taken in a wind tunnel with Reynolds number $Re_{D}$ of 6000–20 000, based on the width of the vertical bars of the grid and the incoming flow velocity. The effect of local drag coefficient $C_{D}$ on the mean velocity profile is discussed first, and then by modifying the vertical bars to obtain a uniform aspect ratio the mean velocity profile is shown to be predictable using the local blockage ratio profile. It is also shown that, at a streamwise location $x=x_{m}$ , the turbulence intensity profile along the vertical direction $u^{prime }(y)$ scales with the wake interaction length $x_{ast ,n}^{peak}=0.21g_{n}^{2}/(unicode[STIX]{x1D6FC}C_{D}w_{n})$ ( $unicode[STIX]{x1D6FC}$ is a constant characterizing the incoming flow condition, and $g_{n}$ , $w_{n}$ are the gap and width of the vertical bars, respectively, at layer $n$ ) such that $(u^{prime }/U_{n})^{2}unicode[STIX]{x1D6FD}^{2}(C_{D}w_{n}/x_{ast ,n}^{peak})^{-1}sim (x_{m}/x_{ast ,n}^{peak})^{b}$ , where $unicode[STIX]{x1D6FD}$ is a constant determined by the free-stream turbulence level, $U_{n}$ is the local mean velocity and $b$ is a dimensionless power law constant. A general framework of grid design method based on these scalings is proposed and discussed. From the evolution of the shear stress coefficient $unicode[STIX]{x1D70C}(x)$ , integral length scale $L(x)$ and the dissipation coefficient $C_{unicode[STIX]{x1D716}}(x)$ , a simple turbulent kinetic energy model is proposed that describes the evolution of our grid generated turbulence field using one centreline measurement and one vertical profile of $u^{prime }(y)$ at the beginning of the evolution. The results calculated from our model agree well with our measurements in the streamwise extent up to $x/Happrox 2.5$ , where $H$ is the height of the grid, suggesting that it might be possible to design some shear flows with desired mean velocity and turbulence intensity profiles by designing the geometry of a passive grid." @default.
