In the non-adiabatic model, the unburnt mixture temperature\/density is not constant and I can&#039;t seem to find a reference showing what temperature\/density is used to calculate these quantities. The partially-premixed model uses mixture fraction polynomials and the adiabatic premixed model defines these values explicitly. I don&#039;t see anything regarding the non-adiabatic premixed combustion model. It appears to be using a single constant temperature, but I am unable to confirm this.<\/p>\n","protected":false},"template":"","class_list":["post-159214","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_old_reply_author_name_id":["Anonymous"],"_bbp_old_is_reply_anonymous_id":["false"],"_btv_view_count":["253"],"_bbp_likes_count":["0"],"_bbp_subscription":["238075"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["159214"],"_bbp_forum_id":["27792"],"_bbp_engagement":["125","197879"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["181227"],"_bbp_last_active_id":["181227"],"_bbp_last_active_time":["2021-07-01 15:47:19"]},"test":"jstrafacpurdue-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/159214","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/159214\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=159214"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
