Keywords: Thust Generation, Biomimetic Foil, Lattice Boltzmann Method

The critical Renolds and Strouhal numbers for the thrust generation of biofoils moving in a very low Reynolds number flow are investigated by using a lattice-Boltzmann method with changing flapping parameters and flapping modes(single, tandem, biplane, wiggling).
