Air-water transfer at wavy interfaces
Gas-water exchange is usually controlled by a thin surface layer in the liquid just beneath the interface. The structure and dynamics of the interface profoundly influence the rate of mass transfer. Of particular importance to environmental and climatical cycles is the large (3 to 5 fold) …

Simulations of thermophoretic deposition in wavy channels
… flow, heat transfer, and soot deposition in wavy channels. The code was then used to study laminar and turbulent flow with Reynolds numbers ranging from 300 to 10,000. The inlet fluid temperature was held at 750 K and the wall temperature was varied from 300 K to 750 K. The first set of …

Variational multi-scale modeling for particle-laden gravity currents over flat and triangular wavy terrains
… particle-laden gravity currents over triangular wavy terrains with changing wave height are further investigated. The effect of the wave height on the flow statistics is discussed. From the good match between our simulation statistics and DNS or experimental data, it demonstrates that the model we …

Investigation of the water-sided shear layer at a wind-driven wavy surface by active thermography
A local, active thermographic measurement method was advanced and used for measuring the mean viscous shear stress in the water-sided boundary layer of a wind driven air-water interface in the presence of water waves, at low wind speeds up to u 10 = (4.8 ± 0.3) m/s. Higher wind speeds of up to u 10 …
