dc.description.abstract | In this project a steady state approach is used to study the stability of surface
nanobubbles in water electrolysis. A two dimensional domain is considered, where
an electrode of length 100 nm is partly covered by a bubble. The results indicates
that a single nanobubble which partially covers the electrode can be stable, as long as
the electrogeneration of hydrogen is suffcient to balance the dissolution of hydrogen
at near the cap of the bubble. The effect of the evaporation rate constant on the
stability of the bubble is investigated, and the results indicates that as evaporation
rate constant is increased from 0.01 m/s to a 100 m/s the needed production of
hydrogen for a given bubble to be stable decreases. For values outside this range
the needed production of hydrogen in converges to a constant value depending on
the geometry of the bubble. | |
