Corona discharge to free surface of' dielectric liquids creates electroh~droci~,namic (EHD) fluid motion due t o a hydroci!mmic drag of running charge movement along the surface. Since it is very difficult for us to observe directly Ihc lliiid motion, the visible arid suspensible tracer w&s frequently used as our usual measure in this research field.Howcver, the tracer impurity is undesirable for leading electrical disturbance as lhe tracer visibility is perferculial.To break the disturbance, a dieleczric liquid tracer of iluoresccncc has been made i n this stu@, arid has beeii examined to see i f it satisfies the intended object. As the rcsults, thc steady EHD iluid motiou induced by surface c(iroiia discharge has been presented in visual impressions.
