Simulação em dinâmica dos fluidos computacional de hélices

Abstract

Propellers are devices used to convert power from a engine to thrust or to the conversion of wind energy into electricity. They are widely used to move various engineering systems, such as: airplanes, helicopters, UAVs, drones, boats, ferries, ships, submarines and even land vehicles. The present work focus on the study of propellers applied to aeronautical engineering systems. This work aims to study the performance of propellers through computational fluid dynamics (CFD). Four different propellers were studied, since small propellers applicable on unmanned aircraft (drones and aircraft models) to manned aircraft. The numerical experiments carried out included the validation of the methods and their comparison with reference experimental results, prediction of the influence of crosswinds on propeller efficiency and influence of geometric elements (ground and axis) on static bench tests.
