摘要: The formation of capillaries in alginate gel is a dissipative process coupled with hydrodynamic flow the immediate neighborhood front formation. due to contraction chains resulting from crosslinking reaction. As shown earlier, capillary only occurs above critical value velocity. In this paper complete theoretical model ratio actual velocity presented. predictions are compared experimental data for copper solutions sodium and dichloride. described as function bulk concentrations, diffusion coefficients, properties molecules rate constant complex For occur, must be neither too small nor large. agreement predicts that restricted finite time interval will not take place if concentration low or high.
