Experimental Study of Clarification of Vortex Structure by Changing Disk Acceleration Time

Authors: Hiroyuki Furukawa, Akihiro Wada, Takashi Watanabe ABSTRACT Disks with two different dimensions were used to clarify the differences in final vortex structures generated by the change in disk acceleration time. The experiment results and calculated results of vortex structures … Continue reading
