Surface coating for reduction of aerodynamic noise and vibrations

TECHNOLOGY SUMMARY

The coating is composed of specially designed and manufactured micro-fibrillar structures.The inventors discovered that the micro-scale fibrillar coating significantly reduced flow separation by reducing the size of the separation bubble and pushing the separation point further downstream. The inventors accomplished this without increasing the turbulent kinetic energy (by-product of texturizing a surface). These results starkly oppose the notion that rough surfaces facilitate flow separation.
