In the first sequence of our experiments, the granule is released from a hopper after a voltage difference V is applied across two short, vertical copper electrodes. As V is increased from zero to 4.8 kV, Q remains practically constant for V V I, In the second sequence of our experiments, V is first set at 4.8 kV; the flow is allowed to start; then V is reduced to the desired voltage. The new Q vs. V curve coincides with the previous Q(V) curve of first sequence, except for V-2 < V < V-1. A simplified one-dimension model is able to explain all the observed features.","PeriodicalId":166080,"journal":{"name":"Powders and Grains 2001","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133249504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
