Hello, <\/p>\n
I am trying to model non premixed nh3\/h2 combustion via EDC (eddy dissipation concept) model. Actually, i am not sure if i achieved to start combustion. I tried several method such as patching, using a different model for the initialization. Sometimes, i observe that the residuals relating to the radicals change during the simulation. I infer that when these residuals change, i achieved to start combustion. In this situation, the iterations take a lot of time and dont proceed. Could you help me about how can i use EDC for my simulation. How should i proceed ? By the way, i am using a reduced kinetic mechanism for the modelling. <\/p>\n
On the other hand, i also used steady diffusion flamelet approach but as far as i know, i have to correct the NOx emission with unsteady laminar flamelet approach. However, when i used unsteady laminar flamelet approach after the solution was obtained from the first approach, i observe that NOx emissions dont change. Everything is same. <\/p>\n
Consequently, i want to model the combustion of a non-premixed nh3\/h2 flame and predict the no emissions. Which way should i follow. <\/p>\n
if anybody helps , i apprecite a lot. <\/p>\n
Thanks. <\/p>\n","protected":false},"template":"","class_list":["post-318357","topic","type-topic","status-closed","hentry","topic-tag-edc","topic-tag-fluent"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["167303","14415"],"_bbp_author_ip":["23.206.193.146"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["1660"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["318357"],"_bbp_forum_id":["27792"],"_bbp_engagement":["14415","167303"],"_bbp_voice_count":["2"],"_bbp_reply_count":["7"],"_bbp_last_reply_id":["326237"],"_bbp_last_active_id":["326237"],"_bbp_last_active_time":["2023-12-04 16:44:04"]},"test":"ozankekul"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/318357","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\/318357\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=318357"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
