Marangoni convection at electrogenerated hydrogen bubbles. - In: Physical chemistry, chemical physics, ISSN 1463-9084, Bd. 20 (2018), 17, S. 11542-11548
Electrolytic gas evolution is a fundamental phenomenon occurring in a large number of industrial applications. In these processes gas bubbles are formed at the electrode from a supersaturated solution. Since dissolved gases can change the surface tension, a gas concentration gradient may cause the surface tension to vary locally at the interface of the gas bubble. Surface tension gradients may also form due to temperature gradients generated by ohmic heating of the electrolyte. In both cases, the resulting shear stress imposes a convection in the electrolyte and the gas bubble (Marangoni eect). This phenomenon may influence the entire electrolytic gas evolution process, e.g., by an enhanced mass transfer. In this study, the first evidence of the Marangoni convection near growing hydrogen bubbles, generated by water electrolysis, is provided. Microscopic high speed imaging was applied to study the evolution of single hydrogen bubbles at a microelectrode. The convection near the interface of the growing bubble was measured by using a time-resolved Particle Tracking Velocimetry (PTV) technique. The results indicate a clear correlation between the magnitude of the Marangoni convection and the electric current.

Preliminary experimental study on applicability of Lorentz force velocimetry in an external magnetic field. - In: Nuclear science and techniques, ISSN 2210-3147, Bd. 29 (2018), 6, Article 80, insges. 8 S.
Lorentz force velocimetry (LFV) is a noncontact technique for measuring electrically conducting fluids based on the principle of electromagnetic induction. This work aims to answer the open and essential question of whether LFV can work properly under a surrounding external magnetic field (ExMF). Two types of ExMFs with different magnetic intensities were examined: a magnetic field with a typical order of 0.4 T generated by a permanent magnet (PM) and another generated by an electromagnet (EM) on the order of 2 T. Two forces, including the magnetostatic force between the ExMF and PM in the LFV, and the Lorentz force generated by the PM in LFV were measured and analyzed in the experiment. In addition, ExMFs of varying strengths were added to the LFV, and the location of the LFV device in the iron cores of the EM was considered. The experimental outcomes demonstrate that it is possible for a LFV device to operate normally under a moderate ExMF. However, the magnetostatic force will account for a high proportion of the measured force, thus inhibiting the normal LFV operation, if the ExMF is too high.
