Hybrid (kinetic-fluid) simulation scheme based on method of characteristics
N. Javaheri, S. Rahimi, H. Abbasi
Certain features of the method of characteristics are of considerable interest in relation with Vlasov simulation [H. Abbasi {\it et al}, Phys. Rev. E \textbf{84}, 036702 (2011)].…
Vlasov model using kinetic phase point trajectories
H. Abbasi, M. H. Jenab, H. Hakimi Pajouh
A method of solution of the collisionless Vlasov equation, by following collisionless phase point trajectories in phase space, is presented. It is shown that by increasing the numb…
Subsonic ion-acoustic solitons
H. Abbasi, H. Hakimi Pajouh, H. A. Shah
In this paper, the nonlinear theory of plasma waves is extended to the plasmas that their equilibrium state are specified by the non-Maxwellian (here kappa) distribution. We believ…
A Computational Fluid Model for Investigation of Plasma Waves and Instabilities
H. Hakimi Pajouh, M. R. Rouhani, H. Abbasi +2
A computational fluid model is developed to study waves and instabilities. A new technique involving initial perturbations in configuration space have been implemented to excite th…
