Some Considerations on the Nitrogen Transfer across Gas-Liquid Iron Interface

Heat transfer across the interface between nanoscale solids and gas.

When solid materials and devices scale down in size, heat transfer from the active region to the gas environment becomes increasingly significant. We show that the heat transfer coefficient across the solid-gas interface behaves very differently when the size of the solid is reduced to the nanoscale, such as that of a single nanowire. Unlike for macroscopic solids, the coefficient is strongly p...

Direct Numerical Simulation of Turbulent Heat Transfer Across a Mobile, Sheared Gas-Liquid Interface

The impact of interfacial dynamics on turbulent heat transfer at a deformable, sheared gas-liquid interface is studied using Direct Numerical Simulation (DNS). The flow system comprises a gas and a liquid phase flowing in opposite directions. The governing equations for the two fluids are alternately solved in separate domains and then coupled at the interface by imposing continuity of velocity...

Effect of Schmidt number on mass transfer across a sheared gas-liquid interface in a wind-driven turbulence

The mass transfer across a sheared gas-liquid interface strongly depends on the Schmidt number. Here we investigate the relationship between mass transfer coefficient on the liquid side, kL, and Schmidt number, Sc, in the wide range of 0.7 ≤ Sc ≤ 1000. We apply a three-dimensional semi direct numerical simulation (SEMI-DNS), in which the mass transfer is solved based on an approximated deconvol...

pH-Dependence and Contributions of The Carbonic Species To Co2 Flux Across The Gas/Liquid Interface

The purpose of this article is to expand the available knowledge on CO2 transfer across the gas/liquid interface in two ways: (1) propose a new mathematical model to describe the pH dependence of CO2 flux across the gas/liquid interface; and (2) propose new relationships that quantitatively describe the contributions of each of the carbonate species ( 3 2CO H , − 3 HCO , and − 2 3 CO ) to total...
