An original technique for quantifying the flow-field characteristics in an electrodeposition process of Zn-SiO2 with Fe

Abstract

The purposed of this article is to introduce a novel approach (uniformity measure, U ) based on entropy theory for measuring the micron-particle blend homogeneity of aqueous electrolytes, which applies directly to the imaging data of flow field and does not require contacting and disturbing it. Effectiveness of the new method has been illustrated on synthetic imaging data. To verify the feasibility of our method for real experimental data, we analyze the flow-field images from electrodeposited Zn-Fe-SiO 2 composite coatings process. The numerical results showed that the potential of proposed method was demonstrated successfully to quantitatively establishes association between plating parameters and flow field characteristics. The possible recommendations are to monitor the deposition of micro-particles during the composite electrodeposition processes and to apply this technique for studying a variety of multiphase mixing problems in which assessment of uniformity is required.
