We analyze the coupling between conduction and radiative heat transfer in near-field regime two coaxial cylinders separated by a vacuum gap. By solving transport equation steady-state metals or polar materials, we highlight flux saturation mechanism for even without non-local effect. In case of this occurs separation distances range 1–10 nm, which can be experimentally explored.

General nonrelativistic theory has been developed and the expressions obtained for tangential (dissipative) radial (conservative) image forces van der Waals (vdW) acting on charged neutral particles when they move parallel to axis of a cylinder with circular cross-section, or in space between coaxial cylinders. Numerical calculations vdW have performed metal (Au) dielectric (Si) materials cylin...

This paper describes dynamic self-assembly of millimeter-sized objects rotating at two parallel fluid interfaces and interacting with one another hydrodynamically, both in the plane of the interface and between the interfaces. The nature of hydrodynamic interactions between the objects rotating on different interfaces and, consequently, the morphologies of the ordered structures that self-assem...

Abstract This article addresses the interaction of two coaxial cylinders separated by a thin fluid layer. The are flexible, have finite length, and subject to vibration mode an Euler–Bernoulli beam. Assuming narrow channel, inviscid linear theoretical approach is carried out, leading new simple tractable analytical expression forces. We show that dimensionless form this matrix reduces single co...

Cylindrical parts are widely used in industry at very different scales from rotating axis for engines to carbon fibres used in composite materials. Consequently, an increasing demand exists for their nondestructive evaluation. The laser ultrasonics technique providing a non-contact generation and detection process is suited for the study of acoustic waves in cylindrical structures. In previous ...
