洛伦兹力测速（LFV）是一种非接触式的液态金属电磁流量测量技术，目前广泛应用于基础研究和冶金领域。到目前为止，LFV的应用仅限于电导率为106 S/m的狭窄液体。在这里，我们证明了LFV可以应用于电导率比液态金属小6个数量级的液体。我们进一步认为，这个范围可以扩展到工业条件下的10 - 3 S/m和实验室条件下的10 - 6 S/m，使LFV适用于大多数实际感兴趣的液体。
Lorentz force velocimetry (LFV) is a noncontact electromagnetic flow measurement technique for liquid metals that is currently used in fundamental research and metallurgy. Up to now, the application of LFV was limited to the narrow class of liquids whose electrical conductivity is of the order 106 S/m. Here, we demonstrate that LFV can be applied to liquids with conductivities up to six orders of magnitude smaller than in liquid metals. We further argue that this range can be extended to 10−3 S/m under industrial and to 10−6 S/m under laboratory conditions making LFV applicable to most liquids of practical interest.
