The G-equation determines where the flame resides at each time step and a chemical-equilibrium assumption is used on the flame front. Everywhere else, detailed chemistry is employed. In this way, we can predict knocking from auto-ignition outside of the flame front (e.g., in the \u201cend gas\u201d) due to compression by the flame propagation. Forte&#8217;s G-Equation model accommodates multi-component fuels and is fully integrated with Forte&#8217;s detailed kinetics solvers.<\/p>\n","protected":false},"template":"","class_list":["post-157349","topic","type-topic","status-publish","hentry","topic-tag-ansys-forte","topic-tag-flame-propagation"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_wp_page_template":["default"],"_bbp_last_active_time":["06-06-2022 20:20"],"_bbp_forum_id":["27784"],"_btv_view_count":["266"],"_bbp_likes_count":["0"]},"test":"articlesansys-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/157349","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/157349\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/media?parent=157349"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
