However, since this is&nbsp; a ternary system, it is essential I specify the effective diffusivity of the species ( CO2 and SO2) in water. I will appreciate any idea on how to specify this using either a UDF or other methods in Fluent.&lt;\/p&gt;&lt;p&gt;Thank you.&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-390960","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["453482","199"],"_bbp_author_ip":["129.244.43.234"],"_btv_view_count":["140"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["390960"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","453482"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["391002"],"_bbp_last_active_id":["391002"],"_bbp_last_active_time":["2024-10-23 09:15:36"]},"test":"75230cb47099387d7b477f6aa073465f9abf8f26"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/390960","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\/390960\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=390960"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
