riblets are micro- and nanostructured surfaces which effect a reduction of drag in the turbulent boundary layer of different flows. riblets have, similarly to the skin of a shark, tiny grooves arranged longitudinally along the flow and these structures reduce the drag up to 8%. the shark utilizes the special structured skin for energy efficient and fast swimming in the water. in technology there are several fields of application for the so-called “shark-skin effect”. the innovative technical surface structures are used in water, air and in every other fluid to benefit from a lot of advantages. computational fluid dynamics (cfd) is a method to analyze fluid flows. with the help of cfd complex flows of all kind can be simulated through numerical calculations on the computer. even complicated flows can be simulated, so that they can be displayed, understood and optimized.
