Abstract: A splitting and a fully discrete second order and a third order semi discrete schemes are modified and adapted for a numerical solution of a hyperbolic system of a one dimensional electrostatic plasma fluid equation. Illustrations as to how the splitting and the NNT (fully discrete) and the semi-discrete (SD3) schemes capture the formation and evolution of ion acoustic solitons and shockwaves were performed. In this study we perform a comparison between a fully discrete NNT and the semi discrete SD3 high resolution schemes and the splitting scheme which is constructed for the first time for a one dimensional plasma systems in the present study. The results indicate that the splitting scheme demonstrates clear superiority over the NNT and SD3 schemes in the soliton solution where the numerical noise of the electron waves is reduced significantly. For the shock wave solution the NNT and SD3 schemes are similar to the splitting scheme but exhibit oscillations at the c!
ontact discontinuity. However the splitting scheme exhibit a smaller computational time than the NNT and SD3 schemes. It is thus advocated that in a one dimensional plasma system for solution and shockwaves simulations the splitting scheme and NNT /SD3 schemes be utilised respectively.
