How to Mesh a Frozen Drone

Richard Hann, Norwegian University of Science and Technology (NTNU) Icing of drones is a severe hazard that significantly limits the usage of autonomous unmanned aerial vehicles (UAVs). Computational fluid dynamic (CFD) methods, originally developed for manned aircraft icing, are an important tool for understanding the effects of icing on UAVs. One of the most challenging tasks for the simulation is the generation of high-quality meshes of complex ice shapes. Atmospheric icing, also called in-cloud icing, occurs when an aircraft encounters supercooled droplets in the atmosphere. Liquid droplets, with a temperature below freezing, turn into ice when they collide with the…
