Flow Structure and fluid transport via advection around pectoral fin of larval ZebraFish
are studied numerically using Immersed Boundary Method, Lagrangian Coherent
Structure, passive particle tracing, vortex core evolution and four statistically defined
mixing numbers. Experimental fish kinematics for nominal swimming case are obtained
from previous researchers and numerically manipulated to analyze the role of different
body motion kinematics, Reynolds number and fin morphology on flow structure and
transport. Hyperbolic strain field and vortex cores are found to be effective particle
transporter and their relative strength are driving force of varying flow structure and fluid
transport. Translation and lateral undulation of fish; as a combination or individual entity,
has coherent advantages and drawbacks significant enough to alter the nature of fluid
advection. Reynolds number increase enhances overall fluid transport and mixing in varying order for different kinematics and nominal bending position of fin has average
transport capability of other artificially induced fin morphology. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2016. / FAU Electronic Theses and Dissertations Collection
