A systematic study of correlation between nose disturbances and evoluted behaviors of asymmetric vortices over slender body models has been conducted. The new flow phenomena have been revealed in which the two-cycle behavior of Cy vs.γ curve for asymmetric vortices flow is continuously changed into one-cycle behavior with increasing of disturbance strength on the model nose tip. This newly found flow phenomenon is important and it provides a physical flow base to the perturbation active control of forebody asymmetric vortices flow.

The asymmetric coefficients of debris flows are quite different in different area: large asymmetric coefficients of debris flow with low resistance; small asymmetric coefficients of debris flow with high resistance. The asymmetric coefficients of debris flow could be used to classify resistance characteristics of debris flow accurately and the resistance law of viscous debris flows was got by asymmetric coefficients.

泥石流的不均匀系数在不同的泥石流地区有很大的不同:不均匀系数小的地区阻力大,而不均匀系数大的地区阻力小,因此可以用不均匀系数划分泥石流沟的阻力特征,从而得到能兼顾所有不同地区的泥石流阻力规律。
