Abstract

Active grids allow for the turbulence in experimental facilities to be tailored through a broad range of turbulence intensities and Reynolds numbers. This work provides an overview of the active grids that presently exist around the globe as well as advances in turbulence research that are a result of their use. Focus is placed on homogeneous turbulent flows, turbulent boundary layers, and model testing.
