Abstract

It is demonstrated that a significant drag reduction for pressure driven flows can be realized by creating separation bubbles through application of spatially distributed heating. These bubbles, whichare driven by the buoyancy force, reduce the direct contact between the main stream and the bounding walls resulting in the reduction of frictional drag. In addition, the movement in the interior of the bubbles driven by the gradients of the buoyancy force results in the creation of a propulsion force, which further reduces the pressure gradient required to drive the specified mass flux through the channel. The global effect, the Super-ThermoHydrophobic effect, is limited to small Reynolds numbers and thus is of potential interest to flows in micro-channels.
