Review Questions

• How does the structure of shark skin contribute to its ability to reduce drag in water?
  • The structure of shark skin features tiny scales known as dermal denticles that disrupt the flow of water around the shark's body. This unique texture creates micro-turbulence which allows the water to adhere more closely to the surface of the skin, reducing drag. By emulating this natural design, technologies can be developed that achieve similar benefits in reducing resistance in various fluid environments, leading to improved efficiency.
• In what ways can the principles of shark skin-inspired drag reduction be applied to renewable energy systems?
  • The principles of shark skin-inspired drag reduction can be applied to renewable energy systems by enhancing the designs of wind turbines and hydroelectric systems. For instance, applying shark skin textures to turbine blades can reduce drag and increase energy capture efficiency. This leads to more effective energy generation and contributes to the overall sustainability of renewable technologies by minimizing their ecological footprint while maximizing performance.
