Notes:
According to analyzing the principle of atmospheric pressure plasma arc (APPA) cleaningmetal surface, a model of heat and mass transfer is put forward with using transient-state heat transferequation about interior heat source and Arrhenius equation of chemical reaction kinetics theory. Withfinite volume method, the one dimensional control differential equation is transformed into discretecontrol equation, which is calculated numerically and analyzed with the using of implicit scheme.Taken cleaning lubricant film as an example and analyzed temperature distribution of cleaning filmon metal surface, the result indicates that the temperature of film has a strong effect on its removal ratewhich improves with increasing temperature. In order to both avoid damaging the workpiece surfaceowing to higher temperature and ensure removal rate of the film, there exists an appropriatetemperature under given calculation conditions
