Emerging redox-active electrolyte chemistries with high viscosity motivate operating RFBs near stoichiometric flow conditions, challenging the utilization of charge capacity due to convective transport limitations. In this work we use numerical modeling to resolve convective transport within RFB tanks that are free-flowing or configured with baffles by solving the laminar vorticity transport equation and transient species diffusion in two dimensions. Dead zones within free-flowing tanks are found to limit capacity utilization, while baffles are shown to enhance capacity utilization by eliminating dead zones for sufficiently long baffles. Utilization is maximized at a particular Péclet number, which depends on the effective length and throat of the serpentine flow path produced by baffles. These effects are shown to result from competition between transverse and longitudinal diffusive transport relative to the local flow.","Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2021-05-01","The student, Yite Wang, accepted the attached license on 2019-04-25 at 09:40.","The student, Yite Wang, submitted this Thesis for approval on 2019-04-25 at 09:55.","This Thesis was approved for publication on 2019-04-25 at 18:01.","DSpace SAF Submission Ingestion Package generated from Vireo submission #13903 on 2019-08-22 at 15:08:35"]},{"key":"dc:format","label":"Dc Format","values":["application/pdf"]},{"key":"dc:title","label":"Title","values":["Numerical investigation of convective transport in redox flow battery tanks"]}]}],"canonical_facts":{"dc:contributor":["Smith, Kyle C."],"dc:creator":["Wang, Yite"],"dc:date":["2019-08-23T20:36:11Z","2021-08-24T09:15:31Z","2019-04-25","2019-05"],"dc:description":["Made available in DSpace on 2019-08-23T20:36:11Z (GMT).
