Measurements were conducted downstream of a square-fractal-element grid at ReL0 = UL0/Î½ = 65, 000, where L0 is the size of the largest element in the grid. The scale-byscale energy budget for gridâ€¦ (More)

A novel square-fractal-element grid was designed in order to increase the downstream measurement range of fractal grid experiments relative to the largest element of the grid. The grid consists of aâ€¦ (More)

Time-resolved planar particle image velocimetry (PIV) was used to analyse the structuring of a turbulent boundary layer into uniform momentum zones (UMZs). The instantaneous peak detection methodâ€¦ (More)

The influence of turbulence on the flow around a wall-mounted cube immersed in a turbulent boundary layer is investigated experimentally with particle image velocimetry and hot-wire anemometry.â€¦ (More)

The evolution of the velocity derivative skewness, S(âˆ‚u/âˆ‚x), is investigated along two streamwise axes and four transverse positions in the wake of a square-fractal-element grid. In the near-field,â€¦ (More)

A turbulent boundary layer subjected to free-stream turbulence is investigated in order to ascertain the scale interactions that dominate the near-wall region. The results are discussed in relationâ€¦ (More)

The influence of a multi-scale fractal-based geometry on the decay of turbulence is investigated by comparing the turbulence produced by a square-fractal-element grid to that produced by two regularâ€¦ (More)

The turbulence produced by two regular square mesh grids is compared to that produced by a square-fractal-element grid composed of an array of small square fractals. All three grids haveâ€¦ (More)

The interaction between a turbulent free-stream and a turbulent boundary layer is investigated through particle image velocimetry measurements. An â€˜interaction layerâ€™ located between 0.12 â‰¤ y/Î´ â‰¤â€¦ (More)
