Asymptotic Methods for Laminar and Turbulent boundary Layers

The minisymposium will have contributions dealing with laminar/turbulent flows- their morphology and structures. Specifically, results would be presented that discuss the very concept of turbulent boundary layers. Also, detailed flow structures arising in mixed convection problem involving velocity and thermal boundary/ interior layers will be a focus of another contribution. This session will also have contributions dealing specifically with temporal and/or spatio-temporal growth of waves in boundary/ interior layers. For example, existence of spatio-temporal growth of waves in boundary layer is established for the first time that is related non-orthogonal modes proposed earlier for Couette and channel flows. The focus will be on receptivity and stability of equilibrium steady flows as well as unsteady bi-directional pipe flows that identifies non-axisymmetric modes.
