Researchers model urban airflows to help improve the design of drones, skyscrapers, and natural ventilation systems  November 25, 2020 Scientists presented the latest findings on modeling and predicting urban airflow at the 73rd Annual Meeting of the American Physical Society’s Division of Fluid Dynamics in the hope of building better buildings, cities, and transportation. According to the scientists in addition to the challenges of traffic congestion and obstacles, critical technology gaps exist in modeling, detecting, and accommodating the dynamic urban local wind fields as well as in precision navigation through uncertain weather conditions. They attached sensors to robotic aircraft to take more cohesive measurements of building wakes, or the disturbed airflow around buildings. They combined […]
