UDV study of a liquid metal vortex flow

Abstract

Vortex singing in tip vortex cavitation under the effect of water quality Xiaoxing Peng, Lianghao Xu, Mingtai Song et al. Abstract. The characteristics of an oscillating vortex flow of liquid metal were studied experimentally using an ultrasound Doppler velocimeter (UDV). The flow was generated by a local alternating magnetic field induced in a rectangular thin cell filled with gallium eutectic. The influence of medium temperature change and stirring on the UDV measurements was considered. The best set of parameters providing the reliability of long-term measurements were determined. The non-monotonic behavior of dependence of the local kinetic energy on the external alternating magnetic field intensity was found.
