A high-order conservative collocation scheme and its application to global shallow-water equations
conservative collocation scheme global shallow-water equations
2015/3/5
In this paper, an efficient and conservative collocation method is proposed and used to develop a global
shallow-water model. Being a nodal type high-order scheme,
the present method solves th...
Hamiltonian approach to the derivation of evolution equations for wave trains in weakly unstable media
Hamiltonian approach evolution equations wave trains weakly unstable media
2009/11/13
The dynamics of weakly nonlinear wave trains in unstable media is studied. This dynamics is investigated in the framework of a broad class of dynamical systems having a Hamiltonian structure. Two diff...
Closure of multi-fluid and kinetic equations for cyclotron-resonant interactions of solar wind ions with Alfvén waves
multi-fluid kinetic equations cyclotron-resonant interactions solar wind ions Alfvén waves
2009/11/13
Based on quasilinear theory, a closure scheme for anisotropic multi-component fluid equations is developed for the wave-particle interactions of ions with electromagnetic Alfvén and ion-cyclotron wave...
