"涡流运动" can be translated into English as "eddy current motion" or simply "eddy motion".
Eddy current motion is often used in contexts related to fluid dynamics or electromagnetic phenomena where eddy currents (induced circular currents) are involved.
Eddy motion is a more general term that describes the swirling or circular movement of fluid (such as air or water) or particles, and it can also be applied metaphorically in other fields.
In scientific or technical contexts, "eddy current motion" might be more precise when referring to electromagnetic-induced eddy currents, while "eddy motion" can be used more broadly for fluid or particle dynamics.
