Research on fluid analysis simulator for elastic oscillating fin of biomimetic underwater robots

This paper describes about research on fluid analysis simulator for elastic oscillating fin of biomimetic underwater robots. Authors has been researching biomimetic underwater vehicle such as flapping wing type. In such system, new concept of fluid analysis simulator is required because of the unique fluid characteristics of elastic oscillating fin. First of all, this paper shows basic characteristics of flapping wing type underwater vehicle as typical case of elastic oscillating fin. Second of all, it shows theoretical problem of conventional fluid analysis simulator, and then, also proposes new concept of fluid analysis simulator for elastic oscillating fin to solve this problem.
