摘要

摘要:随着科学研究的不断深入，目前已有的计算格式仍未能满足人们对流体力学数值模拟研究的高精度、高分辨率、高效率及较强稳定性的要求。针对紧致型WENO格式的计算精度、计算效率及稳定性等性能进行了考察，构造了新型的紧致型WENO格式。数值实验表明：新型紧致WENO格式在保持原紧致WENO格式分辨率的前提下，计算速度有明显提高，计算时间显著减少。因此，研究可以说是对高精度数值方法研究方面的有益补充和探索。

Abstract

Abstract:With the continuous deepening of scientific research

the current calculation schemes is still unable to meet the requirements of high accuracy

high resolution

high efficiency and high stability for numerical simulation of fluid mechanics. In this paper

we investigated the performance of computational accuracy

computational efficiency and stability of compact WENO scheme

and constructed a new compact WENO scheme. The numerical experiment results show that the new compact WENO scheme can improve the calculation speed obviously and reduce the calculation time significantly on the premise of maintaining the resolution of the original compact WENO scheme. Therefore

this study can be regarded as a useful supplement and exploration for the research of high accuracy numerical methods.
