Dispersion of Compressional Waves in Rods of Rectangular Cross Section

Taylor-Aris dispersion in high aspect ratio columns of nearly rectangular cross section

We consider Taylor-Aris dispersion in columns of nearly rectangular cross section of large aspect ratio. We generalize the results of [1] and [2] who showed that the effective diffusion rate for perfectly rectangular cross sections is remarkably different than the diffusion rate between two parallel plates – as the aspect ratio goes to infinity, the effective diffusion rate does not approach th...

Kirchhoff Rods with Nonhomogeneous Cross Section

The Kirchhoff’s theory for thin, inextensible, elastic rods with nonhomogeneous cross section is studied. The Young’s and shear moduli of the rod are considered to vary radially, and it is shown that an analytical solution for the constitutive relations can be obtained for circular cross section and constant Poisson’s ratio. We comment on possible applications of our results.

Oscillation of cylinders of rectangular cross section immersed in fluid

The ability to calculate flows generated by oscillating cylinders immersed in fluid is a cornerstone in microand nanodevice development. In this article, we present a detailed theoretical analysis of the hydrodynamic load experienced by an oscillating rigid cylinder, of arbitrary rectangular cross section, that is immersed in an unbounded viscous fluid. We also consider the formal limit of invi...
