  • Eliminating turbulence in wall bounded flows
    Patent number: 9261119
    Abstract: For eliminating turbulence in a wall bounded flow a section of the flow-bounding wall is moved in the direction of the flow over the flow-bounding wall.

  • ELIMINATING TURBULENCE IN WALL-BOUNDED FLOWS BY DISTORTING THE FLOW VELOCITY DISTRIBUTION IN A DIRECTION PERPENDICULAR TO THE WALL
    Publication number: 20160010803
    Abstract: For eliminating turbulence in a wall-bounded turbulent flow comprising a flow velocity distribution in a direction perpendicular to the wall, the flow velocity distribution in the direction perpendicular to the wall is distorted. This may be done by locally generating additional vortices in the turbulent flow close to the flow-bounding wall, which are distributed over a section of the flow-bounding wall extending in a main flow direction of the turbulent flow, and whose axes predominantly extend parallel to the flow-bounding wall. Distorting the flow velocity distribution in the direction perpendicular to the wall may also be achieved by increasing the flow velocity close to the flow-bounding wall by locally immersing a flow deviating structure in the turbulent flow, or by equalizing the flow velocity distribution in the direction perpendicular to the wall by locally immersing a flow dividing structure in the turbulent flow.
