Scale characterization of jet formation of arrays of multi-source wind generators with measurements and large-eddy simulation
Abstract
Small unmanned and autonomous aerial vehicles are often required to operate within the turbulent atmospheric boundary layer and other degraded environments, where local turbulent behavior can strongly influence stability, control, and navigational performance. Despite the operational importance of these degraded environments, systematic studies of the associated aerodynamic challenges remain limited. One reason is the lack of suitable laboratory settings for repeatable and robust testing of atmospheric like wind conditions. This experimental and computational work characterizes baseline conditions of a modular multi-source wind-generation system that can be used to simulate flight relevant atmospheric conditions. Through complimentary large-eddy simulations and experimental measurements, the jet-formation mechanisms and scaling behavior of the fan array wind generation system are quantified. Important non-dimensional scaling behavior of fan arrays, are quantified, enabling estimation of test regions. The study further investigates how array configuration and the effect of resisting elements influence downwind flow development, offering guidance for the design and optimization of future multi-source wind-generation systems.
