To study the turbulent flow in a channel with wavy wall and its disturbance field, the simultaneous iteration approach for N-S equations is applied to the turbulent flow.
为了研究波形壁湍流及由波形壁引起的扰动场，本文将N-S方程的联立解法应用于湍流。
The problem above can be resolved by the blind synchronization algorithm. The theoretic analysis and experimental results show that the approach can work well on the lower S/N ratio input signals.
理论分析及计算机仿真结果表明，该算法在低信噪比条件下可实现DS/SS信号的盲同步及PN码序列的精确估计。
