Paweł Baj, Shaping Flow with an Active Grid
Generating a flow with specific properties—such as a desired mean velocity profile or turbulence intensity distribution—is often essential in aerodynamic experiments. This is particularly relevant when aiming to replicate conditions like those found in the atmospheric boundary layer. Various techniques exist to achieve such flow conditions, one of which involves the use of an active grid. However, precisely controlling an active grid to reproduce a target flow remains a significant challenge. This presentation introduces a new approach to address this issue, currently in the development phase. The method builds upon earlier techniques used to design non-uniform passive wire grids for generating shear flows.
