Nonlinear Mhd Waves in the Solar Wind Plasma Structures

We investigate the interaction of magnetohydrody-namic waves with plasma density inhomogeneities. Our numerical study of the full MHD equations shows that: (A) Plasma density inhomogeneities are a source of non-linear generation of transverse com-pressive waves by a plane Alfvén wave, and substantially enhance (by about a factor of 2) the generation of the longitudinal compressive waves. (B) At...

Nonlinear coupling of MHD waves in inhomogeneous steady flows

The nonlinear coupling of MHD waves in a cold (β = 0) compressible plasma with a smoothly inhomogeneous low-speed steady flow directed along the magnetic field is considered. The effect is similar to Alfvèn wave phase mixing in a static, inhomogeneous medium and leads to the production of steep transversal gradients in the plasma parameters, which increases dissipation. Transversal gradients in...

Nonlinear evolution of parallel propagating Alfvén waves: Vlasov - MHD simulation

Nonlinear evolution of circularly polarized Alfvén waves are discussed by using the recently developed Vlasov-MHD code, which is a generalized Landaufluid model. The numerical results indicate that as far as the nonlinearity in the system is not so large, the Vlasov-MHD model can validly solve time evolution of the Alfvénic turbulence both in the linear and nonlinear stages. The present Vlasov-...
