I am trying to use ANSYS to model the attenuation of the silencer but am not sure how I would setup this simulation.&lt;\/p&gt;&lt;p&gt;The baffles themselves contain an absorptive material which transfers acoustic energy to thermal energy which is the key element to be able to model and measure. I have the acoustic emissions from the gas turbine which I assume could be used as some input somewhere. Along with this, being able to setup some microphones downstream and upstream of the baffles to see the reduction in noise out of the stack.&lt;\/p&gt;&lt;p&gt;Please let me know if you need anymore information.&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-398562","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27792"],"_bbp_topic_id":["398562"],"_bbp_subscription":["496867","13659"],"_bbp_author_ip":["114.77.146.143"],"_bbp_last_reply_id":["425694"],"_bbp_last_active_id":["425694"],"_bbp_last_active_time":["2025-03-14 12:00:36"],"_bbp_reply_count":["14"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["496867","13659"],"_btv_view_count":["260"],"_bbp_topic_status":["unanswered"]},"test":"noycepmcardiff-ac-uk"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/398562","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\/398562\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=398562"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
