This is a key aspect for a wide range of Chemical Engineering designs with special emphasis on those involving transcritical flows. We introduce a ROM approach based on a non-structured and sparse implementation of the Canonical Polyadic Decomposition of tensors that target abovementioned requirements. It reaches a similar speed with regards to direct use of the full equation of state and provides mean errors about 1 %–5 % without limiting accuracy. Its implementation is done in a standard and portable way, avoiding the need of additional implementation and an easy coupling with open and commercial CFD codes. The method is tested here for CFD but it can be directly applied in any process simulation tool. 000150311 540__ $$9info:eu-repo/semantics/closedAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000150311 590__ $$a4.577$$b2020 000150311 591__ $$aENGINEERING, CHEMICAL$$b36 / 143 = 0.252$$c2020$$dQ2$$eT1 000150311 591__ $$aCHEMISTRY, PHYSICAL$$b63 / 162 = 0.389$$c2020$$dQ2$$eT2 000150311 592__ $$a0.961$$b2020 000150311 593__ $$aChemical Engineering (miscellaneous)$$c2020$$dQ1 000150311 593__ $$aPhysical and Theoretical Chemistry$$c2020$$dQ1 000150311 593__ $$aCondensed Matter Physics$$c2020$$dQ1 000150311 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000150311 700__ $$0(orcid)0000-0001-6906-9143$$aIzquierdo-Estallo, S. 000150311 700__ $$aSierra-Pallares, J. 000150311 773__ $$g165, 104938 (2020), [11 pp]$$pJ. supercrit. fluids$$tJournal of Supercritical Fluids$$x0896-8446 000150311 8564_ $$s2867685$$uhttps://zaguan.unizar.es/record/150311/files/texto_completo.pdf$$yVersión publicada 000150311 8564_ $$s1913442$$uhttps://zaguan.unizar.es/record/150311/files/texto_completo.jpg?subformat=icon$$xicon$$yVersión publicada 000150311 909CO $$ooai:zaguan.unizar.es:150311$$particulos$$pdriver 000150311 951__ $$a2025-10-17-14:14:26 000150311 980__ $$aARTICLE
