• 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
  本文研究了高阶精度加权基本无振荡( weno )格式及其在双曲守恒律方程中的应用，在此基础上作了两个方面的工作：一是针对高频声波问题构造出一种基于保色散关系( drp )的weno有限差分格式，并对计算气动声学( caa )问题的代表性算例进行了大量数值实验，比较了该格式捕捉波数的能力；另外，针对高阶weno格式在处理euler方程的接触间断时精度有所降低的问题，研究了利用界面追踪技术levelset方法和高阶激波捕捉weno格式相结合的一种守恒追踪方法，并且给出有代表性的密度滑移面问题的算例，得到一致高阶精度的数值模拟结果。
