Mosquitos pose a great threat to human health and the economy due to the diseases they carry which kill thousands of humans every year. The goal of this project was to create a tool that could generate turbulence in a wind tunnel, a rectangular duct through which air is blown. This tool was created to create turbulent mixing in the wind tunnel similar to that found in the atmosphere in order to support studies of mosquito behavior when tracking carbon dioxide emitted by humans. This tool is called an active grid and it consists of a grid of individually rotating square paddles. The airflow generated in the wind tunnel by grid motions is being documented using a technique called particle image velocimetry (PIV), which is a technique used to visualizing the movement of air. The goal of these experiments is to figure out which grid motions create an environment in the wind tunnel which best reflects the environment in which mosquitoes exist.
