[1] We investigate the spatial structure of the electron diffuse aurora during the 19 October 1998 storm by comparing drift-loss simulations with precipitating particle data and auroral images. Distributions of precipitating diffuse aurora during magnetic storms depend on variation of the magnetotail electron distributions, electron transport, and electron pitch-angle scattering. In our simulat...

We present in this paper a pressure correction scheme for the drift-flux model combining finite element and finite volume discretizations, which is shown to enjoy essential stability features of the continuous problem: the scheme is conservative, the unknowns are kept within their physical bounds and, in the homogeneous case (i.e. when the drift velocity vanishes), the discrete entropy of the s...

We derive the explicit analytic expression for the Stokes' drift in one dimension in the presence of a dichotomic Markov forcing. For small amplitudes of the forcing, the drift is enhanced, but the enhancement is reduced with increasing frequency of the forcing. On the other hand, a reduction of the drift or even a flux reversal can be induced at larger amplitudes, while the flux is now found t...

Forced convective boiling is of great interest for several applications in the power and process industry, particularly nuclear plants. Under certain nominal, incidental or accidental conditions, a crisis may occur resulting meltdown heating surface. It then essential to predict as accurately possible thermal-hydraulic conditions leading occurrence this crisis. Such an objective cannot reasonab...
