It is a challenge to define boundary conditions for non-local models on bounded domains. The periodic case, which we studied in the previous chapters, is an exception, since we can work with periodic extensions outside of the domain. However, no-flux conditions or Dirichlet or Robin boundary...

volume fraction (in the low solids flux riser) and pressure drop (in the high solids flux riser) that reasonably agree with the experimental data.Fig. 12(b) and (c) shows the effect of the specularity coefficients on radial profiles at low and high solids flux conditions (Shah et al., ...
fluxon splinteringJosephson junctionSine-Gordon equationViscous fluid dynamical calculations require no-slip boundary conditions. Numerical calculations of turbulence, as well as theoretical turbulence closure techniques, often depend upon a spectral decomposition of the flow fields. However, such calculations ...
Here we present a method that yields orthogonal decompositions of incompressible, three-dimensional flow fields and apply it to periodic cylindrical and spherical no-slip boundaries. 关键词: fluxon splintering Josephson junction Sine-Gordon equation DOI: 10.1088/1751-8113/40/4/010 年份: 2007 ...

An approximation of (3) with (4) instead of (3b) written in terms of the ice thickness h and the ice flux q = uh is $$-C\frac{{\left|q\right|}^{m-1}q}{{h}^{m}}-\rho gh{S}_{x}=0\quad {{{\rm{for}}}\,{x}_{d}\le x\le {x}_{g},$$ (5a) $${h}_...
show that the spreading length of the droplets decreases as they move away from the impact point, and the heat transfer rate increases. The internal flow of the droplets weakens as they move away from the impact point, resulting in a decrease in heat...
One critical issue in steady-state and high-performance operation in future tokamak fusion reactors is to develop H-mode operational regimes that mitigate or eliminate the large-amplitude ELMs to decrease the transient heat flux on the divertor and first wall. This paper reviews recent advances in...
