title = "Efficient fluid transport by a bionically inspired micro-flapper: Fluidic investigations using fully coupled finite element simulation",
abstract = "We studied the fluid transport by a bionically inspired micro-flapper fabricated in piezoelectric thin-film technology. The undulatory, wave-like motion of the proposed design is supposed to generate vortex chains in the surrounding fluid resulting in a directed jet stream and, hence, enhanced mass convection and heat transport inside the fluid. Fully-coupled finite element (FE) simulations have been carried out to investigate the fluid transport induced by such an excitation in order to assess the efficiency of the concept. The results show that there is a significant higher net flow for undulation compared to the simple, resonant-like up-and-down motion of the flap, which corroborates the feasibility of the concept.",
