Abstract

The most
efficient designs are found in the nature. Many natural events and processes have
been successfully transferred to the science and technology in order to solve
the problems or to increase the efficiency of the systems. The hydrodynamic
principles were efficiently employed by swimming animals for many years. Excellent
body shapes of fish species have enabled them to continue their generation until
today. The aim of this study is to understand the 2D hydrodynamics of the tope
shark (Galeorhinus galeus) and to analyze the fluid flow around its body
hydrofoil. The hydrofoil of the tope shark (TSH) has been generated using a
real-scale image and digitalized using NURB (Non-uniform B-spline) curves.
ANSYS CFX software has been employed for CFD simulations after suitable meshing
around the TSH. The pressure and velocity area around the shark hydrofoil was
illustrated for different angles of attack and Re numbers. The hydrodynamic
performance variables such as lift, drag and pressure coefficients for the
hydrofoil were analyzed.
