平板上的定常与非定常流动

Steady and Unsteady Flows on a Flat Plate

文章推导了平板突然启动后的非定常流动规律符合高斯误差函数,借鉴平板边界层流动规律,获得了求解平板非定常流动的判别依据,通过临界边界厚度,定义了临界时间,运用分子微团与涡流微团模型探讨了流动状态变化过程。

In this paper,it is deduced that the unsteady flow law of the plate after sudden start-up accords with Gauss error function.Referring to the flow law of plate boundary layer,the discriminant basis for solving unsteady flow of flat plate is obtained.The critical time is defined by the critical boundary thickness.Molecular and eddy microcluster models are used to investigate the process of flow state variation.
