| Popis: | The emerging design of MAVs has arisen a great interest in making research about unsteady Aerodynamics of flapping wings at low Re. When MAVs are flying in real conditions in the atmosphere, they have to face winds' unsteadiness such as continuous turbulence or discrete gusts. The purpose of this thesis is to better understand the physics behind a gust encounter at low Reynolds number. For that, direct numerical simulations are carried out for different transverse gusts with large amplitudes, where the gust velocities are comparable to the freestream velocity. In addition, two different setups are prepared for DNSs and their results are compared with similar experiments from the literature. A third setup for DNS is presented conceptually as well. For the DNS results, a parametric study is done in terms of gust intensity. After analyzing the aerodynamic forces during the gust encounters, some models are developed to predict the lift force during and after the gust encounter. Ingeniería Aeroespacial (Plan 2010) |
