Via this validation study undertaken through the framework of EUROfusion Enabling Research, four state-of-the art models - GBS, Hermes/BOUT++, HESEL and TOKAM3X - are compared to experimental plasma turbulence measurements on the ISTTOK tokamak. Statistical comparisons of simulation and experiment data show that fluid models used here can replicate most of the experiment in terms of of Isat and Vf loat fluctuations despite their differences. Furthermore, it is shown that without including more complex information (like core turbulence information and domain geometry details and magnetic topological aspects) in fluid models, the results recovered vary from their experimental counterparts. Via the simulations using these codes, it is demonstrated that fluid models continue to be a good cost-effective tool in recovering many global aspects of edge plasma behaviour. application/pdf https://susi.usi.ch/global/documents/336955 https://n2t.net/ark:/12658/ffk3336955 https://susi.usi.ch/documents/336955/files/Riva_2021_IOP_Edge turbulence in ISTTOK.pdf eng info:eu-repo/semantics/altIdentifier/issn/0741-3335 info:eu-repo/semantics/altIdentifier/issn/1361-6587 info:eu-repo/semantics/altIdentifier/doi/10.1088/1361-6587/abe21d info:eu-repo/semantics/altIdentifier/ark/12658/ffk3336955 info:eu-repo/semantics/openAccess License undefined Plasma Physics and Controlled Fusion. - 2021, vol. 63, no. 5, p. 055013 info:eu-repo/classification/udc/53 Edge turbulence in ISTTOK : a multi-code fluid validation http://purl.org/coar/resource_type/c_6501
