Longitudinal Impact of Bars of Rectangular Cross-Section

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...

Numerical Simulation of Turbulent Jets with Rectangular Cross-section*

Three-dimensional turbulent jets with rectangular cross-section are simulated with a finite-difference numerical method. The full Navier-Stokes equations are solved at low Reynolds numbers, whereas at the high Reynolds numbers filtered forms of the equations are solved along with a subgrid scale model to approximate effects of the unresolved scales. A 2-N storage, third-order Runge-Kutta scheme...

Experimental Investigation of Mixing in a rectangular cross-section Micromixer

Thin-walled beams: the case of the rectangular cross-section

In this paper we present an asymptotic analysis of the three-dimensional problem for a thin linearly elastic cantilever Ωε = ωε × (0, l) with rectangular cross-section ωε of sides ε and ε 2, as ε goes to zero. Under suitable assumptions on the given loads, we show that the threedimensional problem converges in a variational sense to the classical one-dimensional model for extension, flexure and...

Approximate R.F. Resistance of Rectangular Cross Section Conductors

Small loop antennas such as the AEA-Isoloop sometimes use rectangular cross section conductors, and sometimes use circular cross section tubing for the antenna element. In these antennas, resistive losses are important in determining the efficiency. Here, I approximately calculate the resistance of rectangular cross section elements. For design purposes my results can be summarized by the equat...
