DESCRIPTION:Flapping wings or fins are commonly used by flying or swimming
  animals for locomotion through a fluid. This strategy has also been imple
 mented to design underwater vehicles using flapping propellers for propuls
 ion. To understand such thrust generation mechanisms\, we propose a self-p
 ropelled model\, by considering an elliptical foil for 2D assumption or an
  oblate spheroid for 3D situations\, which undergoes purely vertical sinus
 oidal oscillation. Both linear stability analysis and direct numerical sim
 ulation are applied to investigate how a symmetric motion would lead to a 
 symmetry breaking for the flow around the propeller\, and ultimately resul
 t in irregular or unidirectional locomotion.
