Integrated Propulsion/Lift/Control System for Aircraft and Ship Applications
Abstract
A new method for boundary layer energization and boundary
layer propulsion for use on vehicles moving through
fluids, which comprises mounting small airfoils parallel or
perpendicular to the vehicle's surface, said airfoils being
embedded within the said vehicle's boundary layer and
juxtaposed the surface of said vehicle, said airfoils being
approximately the height of the boundary layer thickness
and exciting said airfoils into flapping oscillation parallel to
the chord plane of said airfoils, said oscillation at a frequency
up to 100 cycles per second at an amplitude up to 20
percent of the chord length of said airfoil, whereby flow
separation is delayed or suppressed which enables the redesign
of said vehicle.

Boundary conditions and stability of a perfectly matched layer for the elastic wave equation in first order form
Duru, K.; Kozdon, JE; Kreiss, G. (2015);In computations, it is now common to surround artificial boundaries of a computational domain with a perfectly matched layer (PML) of finite thickness in order to prevent artificially reflected waves from contaminating a ...
