It gives an authoritative account on the theory of the Euler equations describing a perfect incompressible fluid. First of all, the text derives the Euler equations from a variational principle, and recalls the relations on vorticity and pressure. Vari... (展开全部) 我来说两句 短评 ··· ( ...
perfect incompressible fluidsfinite-element methodsstructure-preserving methodsWe propose a finite-element discretization approach for the incompressible Euler equations which mimics their geometric structure and their variational derivation. In particular, we derive a finite-element method that arises from a ...
PDF/EPUB Tools Share Cite Recommend Abstract Several isotropic, homogeneous cosmological models containing a self-interacting minimally coupled scalar field, a perfect fluid source and cosmological constant are solved. New exact, asymptotically stable solutions with an inflationary regime or a final Friedman...
The exercise of finding suitable metrics for charged perfect fluids of embedding class 1 reduces to findingZ,yfunctions satisfying (14). There is no other reasonable avenue to go forward but to work with (14) since each of Eqs. (7)–(10) consists of at least 3 of the dynamical or geom...

We study the asymptotic limit as the density ratio ρ~-/ρ~+ → 0, where ρ~+ and ρ~- are the densities of two perfect incompressible 2-D/3-D fluids, separated by a surface of discontinuity along which the pressure jump is proportional to the mean curvature of the moving surface. ...
