capable of harnessing energy from wave/wind induced roll oscillations onto a generic floating platform, whose development was initiated with an experimental proof of-concept study that, despite demonstrating the potentialities of the device, also highlighted the need for further developments, aimed at improving its performance and efficiency. This justified a new phase of numerical modelling, where E-Motions was reproduced within the ANSYS (R) AQWATM environment, a potential theory based numerical model widely used in the field of wave energy converter development. The model was setup (first stage) and calibrated (second stage) with experimental data from a proof-of-concept study, carried out on a 1:40 geometric scale, with a good agreement being obtained for the hydrostatic properties (difference below 5%) and hydrodynamic roll response (minimum average error of 2.83 degrees). From a follow-up third stage, focused on comparing eight different hull solutions with similar natural roll periods, it was determined that the half-sphere and trapezoidal prism geometries produced the highest power outputs for the studied conditions (maximum average outputs of nearly 5 kW/m and 8 kW/m, respectively). These two designs were then adapted to a 1:20 geometric scale alongside an updated version of the half-cylinder, which served as a \"control\" case, and subjected to a final stage of numerical modelling centered on assessing the Power Take-Off's influence (namely through variable damping and mass) in their performance. Outcomes from this stage denote the necessity of a careful selection of Power Take-Off mass/damping combinations, as a disproportionate relationship could lead to scenarios where the conversion system would stall on one of the superstructure's sides, moving within a very limited range of the available sliding amplitude. Maximum average power output values reach nearly 24 kW, 30 kW and 18 kW for the half-cylinder, half-sphere and trapezoidal prism, respectively, with a follow-up experimental study being planned for the near future, in order to evaluate the validity of these results.", "subjects" : [ { "otype" : "Classification", "mtid" : 10984, "link" : "/api/classification/10984", "label" : "Gépészmérnöki tudományok", "published" : true, "snippet" : true }, { "otype" : "Classification", "mtid" : 11927, "link" : "/api/classification/11927", "label" : "Környezetmérnöki tudományok", "published" : true, "snippet" : true } ], "keywords" : [ { "otype" : "Keyword", "mtid" : 3164, "link" : "/api/keyword/3164", "label" : "Numerical modelling", "published" : true, "oldId" : 3164, "snippet" : true }, { "otype" : "Keyword", "mtid" : 1015047, "link" : "/api/keyword/1015047", "label" : "Rolling", "published" : true, "oldId" : 1015047, "snippet" : true }, { "otype" : "Keyword", "mtid" : 1315300, "link" : "/api/keyword/1315300", "label" : "Wave energy conversion", "published" : true, "oldId" : 1315300, "snippet" : true }, { "otype" : "Keyword", "mtid" : 1818017, "link" : "/api/keyword/1818017", "label" : "hydrodynamic performance", "published" : true, "snippet" : true }, { "otype" : "Keyword", "mtid" : 2490436, "link" : "/api/keyword/2490436", "label" : "E-Motions", "published" : true, "snippet" : true }, { "otype" : "Keyword", "mtid" : 2490437, "link" : "/api/keyword/2490437", "label" : "Boundary integral element method", "published" : true, "snippet" : true } ], "digital" : null, "printed" : null, "sourceYear" : 2021, "foreignEdition" : true, "foreignLanguage" : true, "fullPublication" : true, "conferencePublication" : false, "nationalOrigin" : null, "missingAuthor" : false, "oaType" : "NONE", "oaCheckDate" : "2022-07-29", "oaFree" : false, "citationCount" : 0, "citationCountUnpublished" : 0, "citationCountWoOther" : 0, "independentCitCountWoOther" : 0, "doiCitationCount" : 0, "wosCitationCount" : 0, "scopusCitationCount" : 0, "independentCitationCount" : 0, "unhandledCitationCount" : 0, "citingPubCount" : 0, "independentCitingPubCount" : 0, "unhandledCitingPubCount" : 0, "citedPubCount" : 3, "citedCount" : 3, "ratings" : [ { "otype" : "SjrRating", "mtid" : 11211225, "link" : "/api/sjrrating/11211225", "label" : "sjr:D1 (2021) Scopus - Energy Engineering and Power Technology ENERGY CONVERSION AND MANAGEMENT 0196-8904", "listPos" : 8, "rankValue" : 0.1, "type" : "journal", "ratingType" : { "otype" : "RatingType", "mtid" : 10002, "link" : "/api/ratingtype/10002", "label" : "sjr", "code" : "sjr", "published" : true, "snippet" : true }, "subject" : { "otype" : "ClassificationExternal", "mtid" : 2102, "link" : "/api/classificationexternal/2102", "label" : "Scopus - Energy Engineering and Power Technology", "published" : true, "oldId" : 2102, "snippet" : true }, "ranking" : "D1", "calculation" : "DIRECT", "published" : true, "snippet" : true } ], "ratingsForSort" : "D1", "hasCitationDuplums" : false, "directInstitutesForSort" : "", "ownerAuthorCount" : 1, "ownerInstituteCount" : 3, "directInstituteCount" : 0, "authorCount" : 4, "contributorCount" : 0, "hasQualityFactor" : true, "link" : "/api/publication/32406776", "label" : "Clemente D. et al.
