What Are Some Techniques Used in Nanotechnology for Drag Reduction?
Several techniques are employed in nanotechnology to achieve drag reduction:
Nanocoatings: These are ultra-thin layers applied to surfaces to reduce friction. Nanocoatings can be hydrophobic or hydrophilic, depending on the application. Nanocomposites: These materials combine nanoparticles with traditional materials to create composites with improved drag-reducing properties. Nanotexturing: The surface of a material is textured at the nanoscale to create patterns that can disrupt fluid flow, reducing drag. Nanoparticles: Added to fluids, nanoparticles can alter the fluid's properties to reduce friction and turbulence.
