The gunnery trainer used films of moving planes.
Part 2. The method of moving planes.
Two sample applications of the method are discussed: we study the tractions on an ellipsoid moving near a plane wall, which provides a more detailed understanding of the well-studied glancing and reversing trajectories in the context of particle sedimentation, and the erosion of bodies by a viscous flow, in which the surface is ablated at a rate proportional to the local viscous shear stress.
In Florida, the U.S. Air Force made preliminary plans to move planes.
He remained calm, had no cough, and left his seat at least twice between Bangkok and Paris to go to the front lavatory; at each move, he passed through the space between the plane wall and seat 25K.
These are: reflection of light from a plane mirror moving at constant velocity, reflection of light from a moving cylinder, reflection of light from a vibrating mirror, reflection of sound from a plane wall and dipole sound generation by an oscillating cylinder in an inviscid flow.
A double-layer integral equation for the surface tractions on a body moving in a viscous fluid is derived which allows for the incorporation of a background flow and/or the presence of a plane wall.
To contribute to the determination of the hydrodynamic interactions between a long straight circular cylindrical particle and flow boundaries, we calculate the wall correction of the drag force exerted on a circular cylinder moving uniformly midway between two parallel plane walls, at very low Reynolds numbers.
The presence of the plane walls causes two basic effects on the droplet velocity: first, the local temperature gradient on the droplet surface is altered by the walls, thereby speeding up or slowing down the droplet; secondly, the walls increase viscous retardation of the moving droplet.
That moving wall is too expensive".
