    "abstract": "A numerical study of the magnetic induction equation has been performed on\nvon Karman type flows. These flows are generated by two co-axial\ncounter-rotating propellers in cylindrical containers. Such devices are\ncurrently used in the von Karman sodium (VKS) experiment designed to study\ndynamo action in an unconstrained flow. The mean velocity fields have been\nmeasured for different configurations and are introduced in a periodic\ncylindrical kinematic dynamo code. Depending on the driving configuration, on\nthe poloidal to toroidal flow ratio and on the conductivity of boundaries, some\nflows are observed to sustain growing magnetic fields for magnetic Reynolds\nnumbers accessible to a sodium experiment. The response of the flow to an\nexternal magnetic field has also been studied: The results are in excellent\nagreement with experimental results in the single propeller case but can differ\nin the two propellers case.",
