【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. [更多还原
