摘要

利用三层理论，研究了非定常自由粘-无粘跨声速相互作用下固体平板上的非经典边界层。本研究的一个特点是选择了边界层中无扰动速度的纵向分量与横向坐标和压力梯度的变异性的二次依赖关系。所考虑的流型与边界层线速度剖面的流型有质的区别。

Mathematical Modeling of an Interactive Transonic Boundary Layer with a Nonlinear Profile of Undisturbed Speed

Using the triple-deck theory, a nonclassical boundary layer over a solid flat plate is investigated in the case of unsteady free viscous–inviscid interactions at transonic speeds. A feature of this study is the choice of the quadratic dependence of the longitudinal component of the unperturbed velocity in the boundary layer on the transverse coordinate and the variability of the pressure gradient. A qualitative difference between the flow pattern in the case considered and the case of a linear velocity profile in the boundary layer is shown.
