Sharks are highly efficient swimmers, thanks to their streamlined bodies and hydrodynamic adaptations. Their sleek shape, tapered snouts, and crescent-shaped tails minimize drag, allowing them to glide through water effortlessly. The rough scales on their skin, known as dermal denticles, disrupt water flow, reducing turbulence and drag while providing protection. Sharks rely on their muscular tails to generate propulsion, enabling rapid acceleration and precise maneuvering. Their exceptional sensory system, including lateral lines, detects changes in water pressure and movement, aiding in hunting and navigation. These hydrodynamic adaptations make sharks formidable and efficient predators in the ocean. In this project, CFD analysis of a shark has been performed using ANSYS CFX. Inlet velocity was set to 4.5 m/s. Turbulence is modeled using SST model. Mesh used has around 1.1 Million elements. ANSYS CFX case file also attached for download.
