Stagnation flow and flame simulations
Axisymmetric jets impinging perpendicularly on a wall are encountered in a variety of real-life situations such as Chemical Vapor Deposition (CVD) processes (Goodwin, 2003). Although the fluid mechanics of the wall-impinging jets are interesting phenomena in their own right, this topic is studied here for two reasons. The first is to assess the extent to which experimental data and numerical da...
متن کاملImpeding hohlraum plasma stagnation in inertial-confinement fusion.
This Letter reports the first time-gated proton radiography of the spatial structure and temporal evolution of how the fill gas compresses the wall blowoff, inhibits plasma jet formation, and impedes plasma stagnation in the hohlraum interior. The potential roles of spontaneously generated electric and magnetic fields in the hohlraum dynamics and capsule implosion are discussed. It is shown tha...
متن کاملConfinement of paramagnetic ions under magnetic field influence: Lorentz- versus concentration gradient force based explanations
Concentration variations observed at circular electrodes with their axis parallel to a magnetic and normal to the gravitational field have previously been attributed elsewhere to the concentration gradient force only. The present paper aims to show that Lorentz force driven convection is a more likely explanation. preprint, finally published in Electrochemistry Communications 9 (2007), 2479–248...
متن کاملRectified ion transport through concentration gradient in homogeneous silica nanochannels.
We investigate the ionic rectifying effect through 4 and 20 nm thick silica nanochannels placed between two ionic solutions of different concentrations. The effect was observed when only a single side of the channel has electric double-layer overlap. The calculation based on Poisson-Nernst-Planck (PNP) theory and a simplified model suggests that the phenomenon result from the accumulation and d...
متن کاملOscillatory Flow Near a Stagnation Point
The classical Hiemenz solution describes incompressible two-dimensional stagnation point flow at a solid wall. We consider an unsteady version of this problem, examining particularly the response close to the wall when the solution at infinity is modulated in time by a periodic factor of specified amplitude and frequency. While this problem has already been tackled in the literature for general...
