Deformation and removal of viscous thin film by submerged jet impingement

Improving Cyclone Efficiency by Recycle and Jet Impingement Streams

In this paper a new process is presented for improving efficiency of cyclone de-dusting systems. The cyclone is coupled with a specially designed cylindrical chamber which includes a rotating tube inside it with air impinging nuzzles, drilled on the peripheral surface of the tube. The nuzzles help in pushing and throwing the particles to the outer radius distances during downward flow of du...

Electrified viscous thin film flow over topography

Deformation of an asymmetric thin film.

Experiments have investigated shape changes of polymer films induced by asymmetric swelling by a chemical vapor. Inspired by recent work on the shaping of elastic sheets by non-Euclidean metrics [Y. Klein, E. Efrati, and E. Sharon, Science 315, 1116 (2007)], we represent the effect of chemical vapors by a change in the target metric tensor. In this problem, unlike that earlier work, the target ...

Aerosol-Jet Printed Thin Film Transistors

Thin film transistors are at the heart of integrated circuits. Modern computer processor chips can contain more than 2 billion transistors. Such chips are currently fabricated by expensive lithography processes and fabrication facilities can cost more than one billion US dollars. In a future era of cheap, disposable electronics such cost structures will not be practical. Printed electronics how...

Hydrodynamics and mass-transfer-limited current distribution for a submerged stationary hemispherical electrode under jet impingement

The stationary hemispherical electrode under a submerged impinging jet is suggested as an experimental system that is amenable to in situ observation and has a uniform current distribution below the mass-transfer-limited value. The present work provides solutions for the steady-state boundary-layer hydrodynamics and convective diffusion. The observation of a boundary layer separation in the pre...
