摘要: 基于三阶ENN格式,通过引入权函数,构造了一种具有四阶或五阶精度的WENN高阶格式,并用此格式数值研究了激波诱导混合增强问题.结果表明,激波诱导方法能进一步加强燃料与空气的混合,这种高阶WENN格式能高分辨地捕捉流场细节.

关键词: WENN格式, 激波诱导, 混合增强

Abstract: Based on the third-order ENN scheme, a fourth-or fifth-order WENN scheme is developed by using the weighted function, and then this scheme is applied to a shock-induced mixing flow. Numerical results show that the degree of mixing enhancement can be increased by the shock-induced technique, and that this WENN scheme exhibits a good resolution for the flow field.

Key words: WENN scheme, shock-induce, mixing enhancement
