Abstract:

This final report documents the findings of our research project which demonstrated through a combination of experimental measurements and numerical simulations that ultrahydrophobic surfaces can be used to delay the transition to turbulence and dramatically reduce drag in both external and internal turbulent flows. These enhancements should have a profound effect on a huge variety of existing technologies, resulting in benefits ranging from a reduction in the pressure drop in pipe flows to an increase in speed and efficiency in surface ships and small submersible vehicles.
