摘要
研究了强迫耗散非线性临界层动力学，得到了强迫耗散非线性临界层的解析解。解析解表明，在含有强迫耗散的条件下，非线性临界层仍有“Ｋｅｌｖｉｎ猫眼”，当时间很大时，“猫眼”趋于定常。强迫耗散因子对非线性临界层激发的“Ｋｅｌｖｉｎ猫眼”的涡度场有重要的调制作用。
The dynamics for a forced dissipative nonlinear critical layer is first dealt with, attaining an analytical solution of such a layer, which suggests that under the forced dissipation, a Kelvin cat′s eye emerges in the layer and the eye tends to be in a steady state as time goes on and the dissipative factor has innegligible modifying effects on a vorticity field as the Kelvin cat′s eye excited in the cirtical layer.
