Stabilité de nappes conductrices de l'électricité avec et sans champ magnétique

Abstract : Although the Kelvin-Helmholtz instability of plane fiuid sheets hasbeen studied by numerous authors for half a century, many questions remain unsolved. The present work is an effort to solve theoretically some of these problems. Two models of an inviscid plane jet in bounded and unbounded inviscid environment have been elaborated. An unexpected result has been the destabilizing effect of solid boundaries. Also, the mathematical difficulty of a spatio-temporal analysis for an unbounded system, due to non meromorphic dispersion relations, has been studied in details and.,.partly solved. Thereafter, the case of a constant and parallel magnetic field., applied to an electrically conducting sheet, has been considered, and revealed that the magnetic field has a stabilizing effect, in contrast with previous results.
