This paper was presented at the 4th Micro and Nano Flows Conference (MNF2014), which was held at University College, London, UK. The conference was organised by Brunel University and supported by the Italian Union of Thermofluiddynamics, IPEM, the Process Intensification Network, the Institution of Mechanical Engineers, the Heat Transfer Society, HEXAG - the Heat Exchange Action Group, and the Energy Institute, ASME Press, LCN London Centre for Nanotechnology, UCL University College London, UCL Engineering, the International NanoScience Community, www.nanopaprika.eu.In the present work, the flow fields induced by the movement of artificial cilia under the effect of
a magnetic field are investigated. In order to obtain almost steady conditions, the set-up consists of fixed cilia
which oscillate under the action of a rotating magnetic field. The aim of the work is to determine under
which geometrical configurations a net flow rate or a global mixing is obtained. The results show that cilia
mounted in the direction of rotation allow net fluid flow, whereas those in radial position have larger
turbulent kinetic energy. Thus, the former could be used as micro-pump, whereas the latter as micro-mixer
