流向磁场下液态金属射流破碎特性的实验研究
Experimental study of the breakup characteristics of liquid metal free jet exposed to a longitudinal magnetic field
摘要
Abstract
To gain a deeper understanding of the magnetohydrodynamic characteristics of liquid metal jets,this study conducted experimental research on the breakup process of a liquid metal GaInSn jet under a flow-aligned magnetic field condition.Based on a self-built liquid metal jet experimental platform,the jet breakup characteristics were experimentally analyzed from four aspects:jet morphology,breakup length,surface disturbance,and droplet distribution.In the absence of a magnetic field,the breakup length increased with the increasing We number.The surface wavelength of the jet approached the critical wavelength under the action of surface tension,and the volume diameter of the jet breakup droplets showed a bimodal structure.When a flow-aligned magnetic field was applied,the droplets formed after jet breakup were subject to vibration attenuation under the action of the flow-aligned magnetic field and exhibited equally sized spherical droplets downstream of the breakup position.The surface wavelength decreased with increasing magnetic field,while the breakup length increased.Three types of influences of the flow-aligned magnetic field on the breakup length of the jet were summarized.关键词
