Dynamic Mesh Method for Two-Dimensional Synthetic Jet

Displacement amplitude scaling of a two-dimensional synthetic jet

A two-dimensional synthetic jet is studied numerically by solving the incompressible, unsteady, Reynolds-averaged, Navier–Stokes equations and using a k-e turbulence model. Rather than a resonant cavity, the synthetic jet is supplied by a fully developed channel flow. Results for two exit geometries, a sharp exit and a rounded exit, and several dimensionless stroke lengths are compared. This st...

DC-mesh: A Contracted High-Dimensional Mesh for Dynamic Clustering

This paper proposes a DC-mesh network that allows requesting nodes to be put into clusters while the requests are sent to a target node, as well as is easy to layout on an LSI chip. To organize the DCmesh, we use the partitioning in the word space based on the Hamming code [1]. We introduce an index scheme, (parity-value,information-value), in the word space, and map it onto a 4-D (dimensional)...

Dynamic mesh refinement for discrete models of jet electro-hydrodynamics

Nowadays, several models of unidimensional fluid jets exploit discrete element methods. In some cases, as for models aiming at describing the electrospinning nanofabrication process of polymer fibers, discrete element methods suffer a non-constant resolution of the jet representation. We develop a dynamic meshrefinement method for the numerical study of the electro-hydrodynamic behavior of char...

Dynamic localization in two low-dimensional synthetic semiconductors

The anomalous temperature dependence of the electrical conductivity (In(a) o(T-~/~) of the low-dimensional synthetic semiconductors (St4N)[Ni(dmit)2] and (mt4N)0.5[Pd(dmit)2] is shown to be a consequence of the thermal vibration of the anions which makes the systems dynamically disordered. For the Ni-compound, the conduction is determined primarily by the number of available carriers. The Pd-co...
