Experiments to determine positions of spherical and long particles and the orientation of long particles can be carried out in a stationary frame by fluidizing particle in a balance of the buoyant weight of the heavier than liquid particle with (1) drag, which will be realized in a vertical tube apparatus (2) hydrodynamic lift (perpendicular to flow, as in a lifting aircraft) which will be real...

A number of closed-form fundamental solutions for generalized unsteady Oseen and Stokes flows associated with arbitrary time-dependent translational and rotational motions have been developed. These solutions are decomposed into two parts corresponding to a longitudinal wave and a transversal wave. As examples of application, the hydrodynamic forces acting on a sphere and on a circular cylinder...

Using the lubrication approximation we investigate two-dimensional steady flow of a thin film of fluid with temperature-dependent viscosity on a uniformly heated or cooled horizontal cylinder, which may be stationary or rotating about its axis, in the case when the Biot number (a measure of heat transfer at the free surface) is large. We show that the film thickness (but not the fluid velocity)...
