Abstract

1,034,370. Boundary layer control. H. LACKENBY. March 8, 1963, No. 11376/66. Divided out of 1,034,075. Heading F2R. [Also in Division B7] In a ship having means for preventing flowseparation, and to boost or accelerate the flow, in the boundary layer at the after body of a ship in forward motion, said means comprises fins on the hull exterior which produce vortices transverse to said flow and cause a mixing of the slow-moving water in the boundary layer with the faster-moving water outside the boundary layer at near the point where the adverse pressure gradient is such that backflow and separation would otherwise take place.
