High Tc superconducting bulk materials for the Lorentz force velocimetry in low conducting and slow flowing fluids.

Number: pap. n. 56

Author(s) : WEIDNER M., HALBEDEL B.

Summary

This paper presents the principle of the Lorentz Force Velocimetry (LFV), a modern method for contactless measurement of the flow velocity in electrically conducting fluids. To reach a high velocity resolution in weak conducting fluids it is necessary to use very strong magnetic fields which the moving fluids penetrate. Hence, High Tc superconducting bulk materials shall be used for the generation of the magnetic field. Compares show that superconductors are able to exceed the flux density of magnet systems with permanent magnets in the LFV. This paper presents the approach and the experimental setup of our first investigations on commercial superconducting bulk material YBa2Cu3O7 (YBCO). The long-term vision of this investigation is to set up a highly reliable and accurate LFV for industrial application, e.g. flow controlling in glass tanks and molten salt plants.
