Actually I am trying to reproduce literature results. My maximum temperature is 100K lower than literature results.&nbsp;<\/p>\n<p><\/p>\n<p>I am wondering is this because my case is not converged yet. all the residuals in my case are flat. The monitor variable kept constant as well. Then I checked mass balance of the combustor, it&#8217;s balanced. Finally I checked the total sensible heat transfer rate. The detailed data set is as follows:<\/p>\n<p><\/p>\n<p>inlet: -58.4W<\/p>\n<p><\/p>\n<p>outlet:-200W<\/p>\n<p><\/p>\n<p>external_wall:-182W<\/p>\n<p><\/p>\n<p>heat of reaction source:461.55 W<\/p>\n<p><\/p>\n<p>net:9.74 W<\/p>\n<p><\/p>\n<p>I know that the net heat transfer rate of the whole system should be 0 if the case is fully converged. However, I can not make it smaller with further iteration.<\/p>\n<p><\/p>\n<p>I am wondering is this an acceptable value to determine convergence or are there any ways to decrease this value further in order to get converged case.<\/p>\n<p><\/p>\n<p>Best regards<\/p>\n<p><\/p>\n<p>Weiqiang<\/p>\n","protected":false},"template":"","class_list":["post-44205","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["16386"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[null],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0"],"_btv_view_count":["888"],"_bbp_subscription":["236081"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["44205"],"_bbp_forum_id":["27792"],"_bbp_engagement":["118","199","22555","156533"],"_bbp_voice_count":["4"],"_bbp_reply_count":["17"],"_bbp_last_reply_id":["115615"],"_bbp_last_active_id":["115615"],"_bbp_last_active_time":["2020-05-25 14:39:21"]},"test":"weiqiang-liu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/44205","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\/44205\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=44205"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
