Özet

The mostefficient designs are found in the nature. Many natural events and processes havebeen successfully transferred to the science and technology in order to solvethe problems or to increase the efficiency of the systems. The hydrodynamicprinciples were efficiently employed by swimming animals for many years. Excellentbody shapes of fish species have enabled them to continue their generation untiltoday. The aim of this study is to understand the 2D hydrodynamics of the topeshark (Galeorhinus galeus) and to analyze the fluid flow around its bodyhydrofoil. The hydrofoil of the tope shark (TSH) has been generated using areal-scale image and digitalized using NURB (Non-uniform B-spline) curves.ANSYS CFX software has been employed for CFD simulations after suitable meshingaround the TSH. The pressure and velocity area around the shark hydrofoil wasillustrated for different angles of attack and Re numbers. The hydrodynamicperformance variables such as lift, drag and pressure coefficients for thehydrofoil were analyzed.
