Euler equation on a fast rotating sphere—Time-averages and zonal flows
Motivated by recent studies in geophysical and planetary sciences, we investigate the PDE-analytical aspects of time-averages for barotropic, inviscid flows on a fast rotating sphere S2. Of particular interest is the incompressible Euler equation. We prove that finite-time-averages of solutions stay close to a subspace of longitude-independent zonal flows. The initial data are unprepared and ca...
متن کاملOn the local existence of the free-surface Euler equation with surface tension
We address the existence of solutions for the free-surface Euler equation with surface tension in a bounded domain. Considering the problem in Lagrangian variables we provide a priori estimates leading to existence of local solutions with initial data in H. Mathematics Subject Classification: 35Q31, 35R35
متن کاملPolygons on a rotating fluid surface.
We report a novel and spectacular instability of a fluid surface in a rotating system. In a flow driven by rotating the bottom plate of a partially filled, stationary cylindrical container, the shape of the free surface can spontaneously break the axial symmetry and assume the form of a polygon rotating rigidly with a speed different from that of the plate. With water, we have observed polygons...
متن کاملOn Discrete Models of the Euler Equation
We consider two discrete models for the Euler equation describing incompressible fluid dynamics. These models are infinite coupled systems of ODEs for the functions uj which can be thought of as wavelet coefficients of the fluid velocity. The first model has been proposed and studied by Katz and Pavlović. The second has been recently discussed by Waleffe and goes back to Obukhov studies of the ...
متن کاملIsentropic Euler equation
An all speed scheme for the Isentropic Euler equation is presented in this paper. When the Mach number tends to zero, the compressible Euler equation converges to its incompressible counterpart, in which the density becomes a constant. Increasing approximation errors and severe stability constraints are the main difficulty in the low Mach regime. The key idea of our all speed scheme is the spec...
