Drag Reduction with Superhydrophobic Surfaces

Problem Statement:

  • Hydrodynamic drag reduction has always been of great interest since it can effectively reduce energy consumption and increase performance in a broad range of applications. With recent advances in nanotechnology, new smart materials described as superhydrophobic have been shown to be capable of reducing drag over a large range of fluid regimes. However, drag reduction trends of these materials are not well understood in turbulent regimes.

Technical Approach:

  • A new generation of superhydrophobic surfaces optimizing drag reduction in turbulent regimes was designed and fabricated.
  • Direct Numerical Simulations are being performed for these materials and numerical tools to accurately predict the drag reduction of superhydrophobic materials in turbulent regimes are being developed.


  • CSED research results could make a critical contribution to several industry applications such as pipelines, cooling systems, irrigation systems, naval transportation, and many others.
