719 Advances in Numerical Modeling and Physical Understanding of Turbulent Boundary-layer Flow Processes

Marco Giovanni Giometto, Columbia University
Boundary-layer flows are ubiquitous in engineering and the environment, where they govern the exchange of energy, momentum, and mass between a fluid and a bounding surface. In particular, boundary layers are important in engineering, geophysics, biology, and other disciplines where heat and mass transfer, phase change, evaporation, skin friction, and turbulent flow structures are often critical for system performance or environmental impact. Advances in computer power, numerical schemes, and parameterizations are enabling accurate simulations of a progressively broader range of boundary-layer flow scales and processes, thus favoring rapid progress in the physical understanding of such systems.
This session will present contemporary themes with regard to numerical modeling techniques and advances in the physical understanding of turbulent boundary-layer flows and related processes. The aim is to bring together researchers from different communities to favor interdisciplinary discussions on theoretical and numerical aspects of the problem. Topics of interest include: parameterizations for subgrid-scale processes, numerical schemes for the simulation of boundary-layer flows, advances in the understanding of equilibrium and non-equilibrium boundary-layers over smooth, transitional, and fully rough surfaces, transition to turbulence, drag reduction techniques, convective heat transfer, evapotranspiration, and atmospheric boundary-layer flow dynamics.
