Let’s say I want to use a stoichiometric fully premixed mixture of hydrogen and air, with the hydrogen mass fraction in the fuel coloumn being 1 and the oxidizer coloumn containing oxygen and nitrogen at 0.233 and 0.767 respectively. The stoichimetric mixture fraction is about 0.0285, so for the Fully Premixed FGM setup, I entered 0.0285 in the blank for “Mixture Fraction Value for Flamelet Generation” and then generated the tables. <\/p>\n

<\/a><\/p>\n

After that, I input entered 0.0285 in the “Mean Mixture Fraction” blank for my velocity inlet of 5 m\/s. After running initially with cold flow and eventually patching a progress variable of 1 over the whole 2d pipe domain, I obtained these results:<\/p>\n

What am I missing with this procedure that’s preventing me from achieving convergence?<\/p>\n","protected":false},"template":"","class_list":["post-368361","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["302346","101181"],"_bbp_author_ip":["23.216.133.166"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["369"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["368361"],"_bbp_forum_id":["27792"],"_bbp_engagement":["101181","302346"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["378056"],"_bbp_last_active_id":["378056"],"_bbp_last_active_time":["2024-08-13 05:15:20"]},"test":"abtharpe42tntech-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/368361","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\/368361\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=368361"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
