On the uncertainty quantification of the unsteady aerodynamics of 2D free falling plates

The 2Dfree fall cards immersed in a fluid was studied using a numerical approach. The motion is characterized by the fluid-body interaction. The model's predictions were validated using experimental and numerical data available in literature. The fillet radius of the plate was considered a random variable characterized by a uniform PDF introducing uncertainties in plate's trajectory. The analysis was focused on finding the median trajectory and error bar for a CI of 95% for tumbling and fluttering
