Optimization of distributed suction for automatic transition control
Optimization of distributed suction for automatic transition control
This paper presents further results of work undertaken at the University of Southampton which has been directed towards the optimization of suction systems for laminar flow control. The ultimate objective of the work is the minimisation of the total net drag on a body by monitoring the state of the flow and automatically controlling of suction applied though the surface of the body. A particular algorithm will be presented which has proved to be very successful in experiments involving the use of two independently controllable panels used to provide suction through porous surfaces on a flat plate mounted in a wind tunnel. It is shown that when this approach is extended to four independent panels (reported here for the first time) then there is a deterioration in repeatability and variance, but that nonetheless the energy cost is consistently reduced.

Abstract
This paper presents further results of work undertaken at the University of Southampton which has been directed towards the optimization of suction systems for laminar flow control. The ultimate objective of the work is the minimisation of the total net drag on a body by monitoring the state of the flow and automatically controlling of suction applied though the surface of the body. A particular algorithm will be presented which has proved to be very successful in experiments involving the use of two independently controllable panels used to provide suction through porous surfaces on a flat plate mounted in a wind tunnel. It is shown that when this approach is extended to four independent panels (reported here for the first time) then there is a deterioration in repeatability and variance, but that nonetheless the energy cost is consistently reduced.
