High Reynolds Number Micro-Bubble and Polymer Drag Reduction Experiments

Abstract

This effort was a continuation of the joint ONR and DARPA programs of the PI and Co-PI's, initiated as part of the DARPA Friction Drag Reduction Program (ATO/TTO). The purpose of the investigation was to examine the physics and engineering of friction drag reduction methods for turbulent boundary layers (TBL) found in hydrodynamic flows. Three methods of friction drag reduction (FDR) were examined: * Polymer Drag Reduction * Micro-bubble Drag Reduction * Air Layer Drag Reduction.
