Towards Ultimate Rayleigh-Benard Convection

PI Janet Scheel, Occidental College
Temperature very near the bottom plate for Rayleigh-Benard Convection flow in a cylindrical container for a Rayleigh number of 3*10^{10}, a Prandtl number of 0.7, and an aspect ratio of 1.0 (i.e., diameter = depth). Dark red corresponds to higher temperature and white to lower temperatures. The image shows that the boundary layer is already becoming intermittently turbulent at this Rayleigh number.

Laminar-Turbulent Transition in Swept-Wing Boundary Layers

PI Lian Duan, Missouri University of Science and Technology
Direct numerical simulations (DNS) capture swept-wing boundary layer transition over a transonic aircraft with laminar flow technology. Near-wall flow visualizations from the DNS confirm the sawtooth nature of transition front as a generic feature of transition due to stationary crossflow vortices regardless of the type of secondary instability. The DNS data provides a clearer interpretation of the surface flow visualizations used in the measurement of transition over swept wings.
