摘要
本文用文献[1]建立的无波动、无自由参数的耗散差分格式(NND格式),对无粘喷流流动进行了数值模拟,并就一典型的自由射流流动,与国外高精度、高分辨率的PLM差分格式(Piecewise-Linear Method)的计算结果和实验结果作了比较,得到了很一致的结果,且所用的计算时间少于PLM格式。
The inviscid jet flow field was Simulated Numerically using the Non-Oscillatory and Non-Free-Parameters Dissipative finite difference scheme which had been established in reference [1]. For a typical Free-jet flow,the comparison of the results obtained by NND scheme and that by Piecewise-Linear Method[2], which is a high resolution and high accuracy finite difference scheme, and the experimental results have been made, it shows that the results in this paper are in good agree-ment with the results obtained by PLM and the experimental results; Particularly, the computer time of NND Scheme is much less than PLMs.
