J0220202 Numerical analysis and consideration of the promotion mechanism of swimming killifish model

Abstract

The present research focuses on the dependence of Reynolds number on propulsion of swimming fish in three-dimensions. Our previous researches of two-dimensions have indicated that a fish speed can be modeled as the combination of thrust part and drag part. The model can be also applied to three-dimensions, thus, it is also found the thrust is almost independent of Reynolds number, but the drag becomes small with increasing Reynolds number.
