COMPUTATIONAL ALGORITHM OF THE DAVYDOV LARGE PARTICLE METHOD FOR CALCULATING LONGITUDINAL OSCILLATIONS OF DUSTY PLASMA
Keywords:
dusty plasma, large particle method, Davydov, computational algorithm, longitudinal oscillations, Poisson equationAbstract
This article presents a computational algorithm for Yu. M. Davydov's large-particle method, adapted for modeling longitudinal oscillations of dusty plasma. The mathematical model is based on the mass and momentum conservation equations for the dust, electron, and ion components, as well as the Poisson equation and the charge kinetics of dust particles. The authors describe in detail the implementation of the Eulerian, Lagrangian, and final stages of the algorithm, taking into account various particle charging regimes—from the theory of constrained orbital motion to the diffusion approximation.
