中文摘要 | 本文是利用高解析度算則求解一維非均勻電子電漿的穩定問題,有別於傳統上利 用特殊函數轉換法求解Vlasov-Poisson方程組,本文是直接利用WENO算則模擬經長時間後 漸漸趨於穩態的Landau阻尼、Two-Stream不穩定問題和多孔Bernstein-Greene-Kruskal 結構等電漿問題。 |
英文摘要 | Accurate finite difference schemes in phase space for solving the Vlasov-Poisson system are presented for the simulation of various stability problems of one-dimensional inhomogeneous electron plasma. Applications of the present method to the simulations of long time evolution of two-stream instability, strong Landau damping and N hole Bernstein-Greene-Kruskal structure are illustrated. |
