VDI 6221:2011-07

This guideline is intended for product and technology developers who want to expand their possibilities for the development of surfaces through the application of biological principles. In the field of technology, boundary layer functionalizations are an essential part of a very wide range of products and applications. In the field of biomimetics, the riblet effect (reduction of friction after the model shark skin) and the lotus effect® (self-cleaning after the model lotus plant)are the most well-known effects. These effects, which influence the flow of fluids, have the potential to save energy when applied to transportation and motion systems.
