Název v původním jazyce

Nonlinear phenomena and qualitative evaluation of risk of clogging in a capillary microreactor under imposed electric field

Popis výsledku v původním jazyce

The studied microsystem consists of two reservoirs containing aqueous electrolytes, a solution of potassium carbonate and a solution of calcium chloride, separated by a microcapillary containing a hydrogel. As the calcium and the carbonate ions diffuse and/or migrate in electric field in the microcapillary, calcium carbonate is formed and the risk of clogging increases at the locations where the concentration product of the calcium and carbonate ions exceeds the CaCO3 solubility product.Two qualitatively different spatio-temporal concentration patterns in the microcapillary of finite length in dependence on the applied difference of the electric potential have been found by means of the dynamical analysis. We have observed patterns with one and two maxima on the spatial profile of reaction rate of the calcium-carbonate interaction. Bifurcation diagram, in which the peak splitting has been clearly detected, was computed in dependence on the imposed gradient of electric potential. The pe
