We practically applied the wnnd scheme to solve scalar conservation laws and euler system in one dimension and n - s equations in two and three dimensions . the numerical results of wnnd schemes indicated good shock transitions without any noticeable oscillations and uniformly high accuracy in smooth regions . the wnnd scheme could catch the detail o f the flow field more particularly 本文应用wnnd格式数值模拟求解了一维标量方程、一维欧拉方程、二维n ? s方程和三维n ? s方程,数值结果表明, wnnd格式在激波附近基本无波动,且在解的光滑区保持空间的统一高阶精度,较之nnd格式, wnnd格式能够更高分辨率的捕捉到流场细节。
