Accelerated laminar viscous incompressible flow along a flat ribbed surface
Abstract
The analysis deals with the flow generated by abruptly accelerating a ribbed surface in its own plane. The infinitely thin equidistant ribs are normal to the plane which constitutes their base. The flow occurs in the direction of the ribs. It is shown that after a short period of time, the friction drag coefficient becomes smaller than in the case of the analogous flow along a surface without ribs.
