Drag reduction effect by streamwise traveling wave-like wall-surface heating/cooling in a turbulent channel flow

Journal of Thermal Science and Technology
We conduct a direct numerical simulation of a turbulent channel flow controlled using the buoyancy force induced by streamwise traveling wave-like wall-surface heating/cooling under a constant pressure gradient condition.

Early Miocene Exhumation of High-Pressure Rocks in the Himalaya: A Response to Reduced India-Asia Convergence Velocity

Frontiers in Earth Science, 2021
Low-viscosity channel flow, originating from a melt-weakened mid-crustal layer, is one of the most popular tectonic models to explain the exhumation of deep-seated rocks in the Greater Himalayan Sequence (GHS). The driving mechanism of such channel flow,
