Experimental and Numerical Study on Polymer Ablated Arc Characteristics with One Side Flow Outlet Model
An experimental and numerical study was conducted on the polymer ablated arc with an electrode configuration of a one-side gas flow outlet model. The polymers used for molded case circuit breaker and gas circuit breaker, such as PA6, POM, and PTFE, were compared. In the experiment, the polymer ablated arc characteristics of arc voltage, arc energy, and mass loss of polymer by ablation were measured. In the numerical calculation, an electromagnetic thermofluid simulation for polymer ablated arc was conducted using a calculation model of similar structure but without using empirical values. In the model used, the polymer ablation was treated as the pyrolytic ablation rather the photodegraded ablation because the arc plasma was definitely in contact with the polymer. The comparison of both experiment and numerical simulation results revealed the relationship between arc energy and mass loss of polymer by ablation, and these values agreed well. Therefore, the numerical simulation model with pyrolytic ablation developed was indicated to be valid for predicting the polymer ablated arc with plasma-polymer contact.
期刊介绍：
Publishing original papers on fundamental and applied research in plasma chemistry and plasma processing, the scope of this journal includes processing plasmas ranging from non-thermal plasmas to thermal plasmas, and fundamental plasma studies as well as studies of specific plasma applications. Such applications include but are not limited to plasma catalysis, environmental processing including treatment of liquids and gases, biological applications of plasmas including plasma medicine and agriculture, surface modification and deposition, powder and nanostructure synthesis, energy applications including plasma combustion and reforming, resource recovery, coupling of plasmas and electrochemistry, and plasma etching. Studies of chemical kinetics in plasmas, and the interactions of plasmas with surfaces are also solicited. It is essential that submissions include substantial consideration of the role of the plasma, for example, the relevant plasma chemistry, plasma physics or plasma–surface interactions; manuscripts that consider solely the properties of materials or substances processed using a plasma are not within the journal’s scope.
