A quasi-isotropic, quasi-homogeneous turbulence generated by an oscillating-grid, spatially decays according to power law ofnuu∝Z?, whereuis the root mean square (rms) horizontal velocity,Zis the vertical distance from the grid andnu=1. However, the findings of Nokes and Yi indicate that as the stroke of oscillation increases, the power lawnu≠1 and does not follow the established decay law equation of Hopfinger. This paper investigates the characteristics of the turbulence that are generated using larger strokesS/M=1.6 and 2 and compares with that obtained using aS/M=0.8, which is the stroke used when the equation was developed. Measurements of the grid-generated turbulence in a water tank were taken using particle image velocimetry (PIV). The results showed that the homogeneity occurred at distance beyond 2.5 mesh spacings away from the grid midplane, independent of the stroke and the frequency of oscillation. Within this region, the turbulent kinetic energy distribution was quasi-homogeneous, and the secondary mean flow is negligible. The statistical characteristics of the measured turbulence confirmed that althoughnu decreases as stroke increases, the grid-turbulence generated atS/M=1.6 and 2 obeys the universal decay law.
