  1. The modified method of characteristics with adjusted advection based on weno interpolation for nonlinear convection - diffusion equation

    對流擴散方程的基於加權本質非振蕩插值的調整對流的修正特徵差分解法
  2. In this paper, high - order accurate weighted essentially non - oscillatory ( weno ) schemes are investigated and their applications in hyperbolic conservation laws are discussed. based on this, a new weno difference scheme which based on dispersion - relation - preserving relation is developed, and representative test cases with this scheme for computational aeroacoustics ( caa ) problems has been implemented and compared in order to test capability of wave capturing ; in addition, weno schemes generally do not converge at high order in the presence of contact discontinuity of euler equations, so a conservative front tracking technique coupling weno schemes and level set method to simulate the translating density profile is presented here, and numerical simulation with this technique for representative test case has been implemented and results show the desired accuracy

    本文研究了高階精度加權基本無振蕩( weno )格式及其在雙曲守恆律方程中的應用,在此基礎上作了兩個方面的工作:一是針對高頻聲波問題構造出一種基於保色散關系( drp )的weno有限差分格式,並對計算氣動聲學( caa )問題的代表性算例進行了大量數值實驗,比較了該格式捕捉波數的能力;另外,針對高階weno格式在處理euler方程的接觸間斷時精度有所降低的問題,研究了利用界面追蹤技術levelset方法和高階激波捕捉weno格式相結合的一種守恆追蹤方法,並且給出有代表性的密度滑移面問題的算例,得到一致高階精度的數值模擬結果。
  3. Eno and weno are two types of representatives of high resolution schemes now

    Eno格式和weno格式是目前應用非常廣的高解析度格式。
  4. Numerical simulation for 1d dam - break flows with weno scheme

    格式的一維潰壩波的數值計算
  5. In this paper, we analyzed and discussed the basic principle of the recently developed high order accuracy finite difference schemes ? eno schemes and weno schemes. based on 2nd order nnd schemes, we introduced a 3rd order wnnd scheme with jiang and shu ' s " weighted " idea and a tvd runge - kutta time discretization method

    對于新近發展起來的eno格式和weno格式,本文分析並討論了其基本構造原理,並且在二階nnd格式的基礎上,利用jiang和shu的加權思想和具有tvd性質的runge - kutta時間離散方法,建立了時、空三階精度的wnnd格式。
