The current state of the art relies heavily on the use of efficiency functions to compensate for impaired wrinkling of the thickened flame. However in practice these functions can involve parameters that are difficult to determine, perform poorly outside of certain ranges or require a posteriori analysis to evaluate performance. An alternative based on a generalised thickening is evaluated across a range of canonical configurations. The approach is demonstrated to perform well across a large range of thickening factors in capturing phenomena such as localised quenching and pinch off as well as generation of flame surface. Including good performance even in the case of large flame dynamics under acoustic forcing where the model has a clear advantage over DNS in achieving grid independence. Finally the approach is unified into an Large Eddy Simulation/Adaptive Mesh Refinement framework and applied to a turbulent Bunsen flame. The results show that even if the internal flame structure is poorly resolved on the original mesh, the global system behaviour is well predicted and compares favourably with other approaches. 000166119 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttps://creativecommons.org/licenses/by/4.0/deed.es 000166119 590__ $$a2.0$$b2023 000166119 591__ $$aTHERMODYNAMICS$$b37 / 78 = 0.474$$c2023$$dQ2$$eT2 000166119 591__ $$aMECHANICS$$b91 / 170 = 0.535$$c2023$$dQ3$$eT2 000166119 592__ $$a0.779$$b2023 000166119 593__ $$aChemical Engineering (miscellaneous)$$c2023$$dQ1 000166119 593__ $$aPhysics and Astronomy (miscellaneous)$$c2023$$dQ1 000166119 593__ $$aPhysical and Theoretical Chemistry$$c2023$$dQ1 000166119 594__ $$a5.7$$b2023 000166119 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000166119 700__ $$0(orcid)0000-0001-8342-6573$$aNavarro-Martinez, Salvador 000166119 773__ $$g111, 3 (2023), 897-927$$pFlow turbul. combust.$$tFlow, Turbulence and Combustion$$x1386-6184 000166119 8564_ $$s2878438$$uhttps://zaguan.unizar.es/record/166119/files/texto_completo.pdf$$yVersión publicada 000166119 8564_ $$s1459089$$uhttps://zaguan.unizar.es/record/166119/files/texto_completo.jpg?subformat=icon$$xicon$$yVersión publicada 000166119 909CO $$ooai:zaguan.unizar.es:166119$$particulos$$pdriver 000166119 951__ $$a2026-01-20-14:18:02 000166119 980__ $$aARTICLE
