The model employs one-dimensional fluid description of the plasma in argon and copper vapour at atmospheric pressure and the heat transfer in the electrodes made of copper. The solution of the particle and energy conservation of electrons and heavy particles is coupled with the solution of the Poisson equation, from which the self-consistent electric field is obtained. The operation of the non-refractory cathode is based on thermo-field emission. Heat fluxes from the plasma to the electrodes are considered so that a phase change and evaporation from the cathode and a release of copper atoms into the plasma are taken into account. The influence of the copper atoms and ions on the plasma properties is analysed and discussed. The model\u0027s predictions are compared with experimental data and a qualitative agreement is obtained besides the restrictions of the one-dimensional fluid model.\u003C\/p\u003E\n","url":"https:\/\/www.inptdat.de\/dataset\/unified-modelling-low-current-short-length-arcs-between-copper-electrodes","state":"Active","log_message":"Update to resource Short-length arcs between copper electrodes_Fig.8_2","private":true,"revision_timestamp":"Thu, 09\/16\/2021 - 15:16","metadata_created":"Wed, 08\/12\/2020 - 10:03","metadata_modified":"Thu, 09\/16\/2021 - 15:16","creator_user_id":"0e27023c-5517-4b3f-b96e-c939dc6a74ff","type":"Dataset","resources":[{"id":"d35e2b2d-227f-4a28-86d7-1a4d1eacc5c5","revision_id":"","url":"https:\/\/www.inptdat.de\/system\/files\/node248_Fig1.csv","description":"\u003Cp\u003EThe calculated current density due to thermo-field emission of electrons from a copper surface (work function of copper 4.5 eV).\u003C\/p\u003E\n","format":"csv","state":"Active","revision_timestamp":"Fri, 06\/11\/2021 - 12:15","name":"Short-length arcs between copper electrodes_Fig.1","mimetype":"text\/csv","size":"911 bytes","created":"Fri, 08\/28\/2020 - 12:58","resource_group_id":"8213480c-adb6-4936-8811-f1dd8f8b3a2f","last_modified":"Date changed  Fri, 06\/11\/2021 - 12:15"},{"id":"b138ce33-761d-4765-a114-e56688e780d1","revision_id":"","url":"https:\/\/www.inptdat.de\/system\/files\/node248_Fig3_0.csv","description":"\u003Cp\u003EBoltzmann plots for three radial positions in the midplane of the arc at arc current of 3.4 A.\u003C\/p\u003E\n","format":"csv","state":"Active","revision_timestamp":"Fri, 06\/11\/2021 - 12:36","name":"Short-length arcs between copper electrodes_Fig.3","mimetype":"text\/csv","size":"539 bytes","created":"Mon, 08\/31\/2020 - 09:57","resource_group_id":"8213480c-adb6-4936-8811-f1dd8f8b3a2f","last_modified":"Date changed  Fri, 06\/11\/2021 - 12:36"},{"id":"ec45b21c-c0f3-4404-ae6c-daae8e8f4d4e","revision_id":"","url":"https:\/\/www.inptdat.de\/system\/files\/node248_Fig4.csv","description":"\u003Cp\u003ERadial distribution of the excitation temperature T in the midplane of the arc at 3.5 A.
