Experimental analysis on metamaterials boundary layers by means of a pantographic structure under large deformations

نویسندگان

چکیده

In this work, the dynamical behavior of a pantographic structure undergoing large deformations is analyzed. A harmonic force applied on structure, while its motion in time recorded by means high-speed camera system. The resulting displacement field obtained via digital image correlation (DIC) method for whole domain. parametric study with respect to amplitude imposed exhibits appearance non-linear effects system response as well presence so-called boundary layer region. Such geometric nonlinearities are paramount interest studying accuracy potential computational model. Boundary layers known be effected microstructure, but their roles yet comprehended. experimental results work may used benchmark case modeling metamaterials.

Boundary Layers and Heat Transfer on a Rotating Rough Disk

The study of flow and heat transfer over rotating circular disks is of great practical importance in understanding the cooling of rotatory machinery such as turbines, electric motors and design and manufacturing of computer disk drives. This paper presents an analysis of the flow and heat transfer over a heated infinite permeable rough disk. Boundary-layer approximation reduces the elliptic Nav...

Pressure gradient effects on the large-scale structure of turbulent boundary layers

Research into high-Reynolds-number turbulent boundary layers in recent years has brought about a renewed interest in the larger-scale structures. It is now known that these structures emerge more prominently in the outer region not only due to increased Reynolds number (Metzger & Klewicki, Phys. Fluids, vol. 13(3), 2001, pp. 692–701; Hutchins & Marusic, J. Fluid Mech., vol. 579, 2007, pp. 1–28)...
