A drop of a viscous fluid in an infinite reservoir of another fluid will move under its own weight if the surrounding fluid has different density. This paper is concerned with steady motions, i.e. the motions of the two fluids are indeFendent of time with respect to an observer attached to the interface between them. We assume that the shape of this bounding surface is governed by surface tension.

We present an approach to generating volumetric meshes from closed triangulated surface meshes. The approach initially generates a structured hexahedral mesh based on the bounding box of a surface. Each hexahedron is represented by five tetrahedrons. The complexity of the initial tetrahedral mesh is user-defined. In a second step various subdivision methods can be optionally applied to the tetr...

In the present investigation the disturbances in a homogeneous transversely isotropic magneto-Visco thermoelastic rotating medium with two temperature due to thermomechanical sources has been addressed. The thermoelasticity theories developed by Green-Naghdi (Type II and Type III) both with and without energy dissipation has been applied to the thermomechanical sources. The Laplace and Fourier ...

The volume of a solid enclosed by a recursive subdivision surface can be approximated based on the closed-form representation of regular parts of the subdivision surface and a tight estimate of the local convex hull near extraordinary points. The approach presented is eecient, i.e. non-exponential, and robust in that it yields rapidly contracting error bounding boxes. An extension to measuring ...

We describe direct imaging measurements of the collective and relative diffusion of two colloidal spheres near a flat plate. The bounding surface modifies the spheres' dynamics, even at separations of tens of radii. This behavior is captured by a stokeslet analysis of fluid flow driven by the spheres' and wall's no-slip boundary conditions. In particular, this analysis reveals surprising asymme...

The present paper is concerned with  the investigation of disturbances in a homogeneous  transversely isotropic thermoelastic rotating  medium with two temperatures, in the presence of the combined effects of   Hall currents and magnetic field due to thermomechanical sources. The formulation is applied to the thermoelasticity theories developed by Green-Naghdi Theories of Type-II and Type-III. ...
