摘要

This research explores the efficacy of high-frequency traveling magnetic fields in driving and heating low-conducting liquids, crucial for applications in the chemical and metallurgical industries. In consideration of Joule heating effects, the study investigates the impact of this magnetic field on four electrolytic solutions with varying conductivities using a novel experimental setup: sulfuric acid (H2SO4), sodium hydroxide (NaOH), sodium chloride (NaCl), and ionic liquid ([Bmim]BF4). The results demonstrate that high-frequency magnetic fields can induce significant volumetric forces and promote rapid, uniform fluid motion with speeds up to several centimeters per second. The technology, characterized by its non-contact nature and pollution-free operation, proves especially advantageous for processes requiring high efficiency and environmental safety. Our findings suggest extensive potential for enhancing three-phase transfer processes in diverse industrial contexts, promoting a shift from traditional mechanical stirring methods to electromagnetic solutions.
