The PIs will utilize techniques of nonlinear dynamics to characterize parameter spaces supporting various solutions. This will help to predict stable boundary layers. Systems of ordinary differential equations (ODE) will be used along with more complete partial equation (PDE) descriptions of these systems. The project will analyze both the simpler ODE systems and the PDE systems. Multidimensional bifurcation and regime diagrams will be developed to describe the role of various parameters in determining the solution regimes.

PI将利用非线性动力学技术来表征支持各种解决方案的参数空间。这将有助于预报稳定的边界层。将使用常微分方程组(ODE)以及对这些系统的更完整的偏方程(PDE)描述。该项目将分析较简单的ODE系统和PDE系统。将开发多维分叉和区域图来描述各种参数在确定解区域中的作用。
