Interfacial instability on bubble surface during chemosorption

نویسنده

  • S. P. Karlov
چکیده

Interference laser spectroscopy was used to study the macrokinetics of absorption of carbon dioxide by aqueous solutions of chemisorbents. Chemisorption was shown to be a complex and multistage process. Its evolution included the occurrence of a diffusion-controlled chemical reaction close to the interphase boundary, the appearance of instability, and the development of convection in the liquid phase. The main rules governing stability loss during chemisorption were considered.

Rapid evaporation at the superheat limit

In an experimental investigation of the transient processes that occur when a single droplet of butane at the superheat limit vaporizes explosively, short-exposure photographs and fast-response pressure measurements have been used to construct a description of the complete explosion process. It is observed that only a single bubble forms within the drop during each explosion, and that the growt...

Effect of surface tension on the Rayleigh-Taylor and Richtmyer-Meshkov instability induced nonlinear structure at two fluid interface and their stabilization

The effect of surface tension on the Rayleigh-Taylor (RT) instability and Richtmyer – Meshkov (RM) instability induced development of nonlinear structures like spike and bubble at two fluid interface have been investigated .In case of RT instability, the surface tension reduces the velocity of the tip of both the bubble and the spike by the factor (1-k /3 kc ) where, kc =(h-l)g/T .For k > 3 k...

The effect of soluble surfactant on the transient motion of a buoyancy-driven bubble

The effect of soluble surfactants on the unsteady motion and deformation of a bubble rising in an otherwise quiescent liquid contained in an axisymmetric tube is computationally studied by using a finite-difference/front-tracking method. The unsteady incompressible flow equations are solved fully coupled with the evolution equations of bulk and interfacial surfactant concentrations. The surface...

Bubble Pinch-off and Breakup Due to Instability in Micro-jettting

This paper presents the dynamics of microbubbles that are pinched-off and breakup in micro-jetting. A microjet is generated in two bubble interaction when a laser induced bubble is impacting a static gas bubble in a microchannel. Gas layers with a height of hundreds of nanometer are pinched off from the accelerated gas bubble wall during the jetting process. They are further modified by surface...
