Interfacial instability on bubble surface during chemosorption
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...
متن کاملThermoelastic Instability in Planar Solidification
-A linear perturbation method is used to examine the stability of a unidirectional solidification problem in which a liquid, initially at the melting temperature, becomes solidified by heat transfer across a pressure-dependent thermal contact resistance to a plane mold. The contact pressure will be influenced by thermal distortion in response to the instantaneous temperature field in the solidi...
متن کاملShear stabilization of morphological instability during directional solidification
A linear stability analysis is performed on the interface formed during the directional solidification of a dilute binary alloy in the presence of a time-periodic flow. In general, the flow is generated by translating the crystal relative to the far-field flow in elliptical orbits parallel to the interface. The presence of this complex, unsteady flow can either stabilize or destabilize the syst...

LLE Review, Volume 105 26 Introduction In inertial fusion experiments, it is energetically advantageous to form the fuel into a solid shell before compression.1 Current cryogenic target experiments on OMEGA are being performed with pure deuterium (D2) as the fuel. 2 Future cryogenic target experiments will be performed with an equimolar solid mixture of deuterium and tritium (D-T). An equilibri...
متن کاملSoret Dufour Driven Thermosolutal Instability of Darcy-maxwell Fluid
Linear stability of double diffusive convection of Darcy-Maxwell fluid with Soret and Dufour effects is investigated. The effects of the Soret and Dufour numbers, Lewis number, relaxation time and solutal Darcy Rayleigh number on the stationary and oscillatory convection are presented graphically. The Dufour number enhances the stability of Darcy-Maxwell fluid for stationary convection while it...
