Abstract:

The work under this grant has consisted of a fairly broadly aimed theoretical analysis along several fronts with the aim of understanding the basic mechanisms responsible for the creation of turbulence in a boundary layer and the possible use of this knowledge to explain observed phenomena of turbulent drag reduction through polymer addition, etc., as well as to be able to propose new and improved drag reducing methods. The work has progressed along three main lines of attack which are a Theoretical modeling of boundary-layer turbulence b Mechanisms involved in laminar-turbulent transition in a boundary layer and c Drag reduction mechanisms.
