Evaluation of the Advanced Erosion Impacts on the Medium Motion Inside а Microelectrode

Abstract

The impact of the inside erosion of a microelectrode on the cooling medium motion is considered in the paper. Taking into account the equation of continuity for a fluid flow inside the microelectrode cannel, the analytical relation between the pressure gradient flow and the number of defects (holes and cavities) of the internal cooling surface is received. Driven by this ratio, the method of a early detection of the defect nucleation and the defect dynamics inside the microelectrode cannel is proposed, and a simple analytical motion model for the cooling medium is build. The motion variables are evaluated, and an effective way to remove the soil particles from the erosion area by a medium flowing is offer. The findings are in good agreement with the studies elsewhere and experimental data of other researchers.
