Evaluation of Ceiling Fan Blade Angle Performance using CFD

In the early days of aeronautics the flight of birds has stimulated scientists and engineers in the research and development of aircraft. Much has been learnt from nature and pioneers in the aeronautical field have studied the flight of birds. Birds move from one place to another by driving their wings in air. The motions of the bird in the air consist of flapping flight as well as gliding and soaring flight. Investigations on the aerodynamic characteristics of birds have been conducted for a variety of purposes. For example, an issue is formation flight of the birds as an energy saving mechanism during migration. Other investigations deal with aerodynamic characteristics of bird wings in steady flow conditions. In this simulation, the bird configuration is modelled at a fixed position and the flow does not change with time. However, there are also unsteady flight conditions, like yawing and rolling motions. Such movements produce a response of the airflow at the wing changing with time. This unsteady airflow affects the lateral-directional stability characteristics of birds.
