This study presents the experimental analysis of air flow vortex propagation through porous screens. Our research was conducted with a new and unique experimental setup for measuring and visualizing air vortex flow through porous media. A custom-made, high-precision vortex generator provided a variety of velocity profiles for vortex generation with an unprecedented level of precision. The flow field was captured with the use of a fog generator and a high-speed CCD camera. The porous screens were constructed out of acrylic rods with various orientations, thickness, and porosities from rod separation. The results presented in this paper show the effect of porosity and air injection velocity on the behavior of air flow (separation, accumulation), and the transport phenomena of vortex flow through porous screens.
