This will be significant when working with high-temperature conjugate heat transfer (CHT) cases, as radiant heat flux can become a dominant factor compared to convection or conduction.<\/p>\n<p>You\u2019ll learn two main methods for defining internal radiation: through the fluid-solid interface or using wall conditions and we\u2019ll see how to define internal emissivity values.<\/p>\n<p>Please refer to the documentation to understand this further: <a href=\"https:\/\/ansyshelp.ansys.com\/account\/secured?returnurl=\/Views\/Secured\/corp\/v232\/en\/discovery_beta\/UDA\/beta\/c_Internal_Radiation.html\">Internal Radiation<\/a><\/p>\n<p><iframe loading=\"lazy\" class=\"vidyard_iframe\" src=\"\/\/play.vidyard.com\/k1StsztLymkYchV5tK7CQF.html?\" width=\"640\" height=\"360\" frameborder=\"0\"><\/iframe><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-183476\" src=\"https:\/\/innovationspace.ansys.com\/knowledge\/wp-content\/uploads\/sites\/4\/2024\/09\/AISTile-1-275x300.png\" alt=\"\" width=\"275\" height=\"300\" srcset=\"https:\/\/innovationspace.ansys.com\/knowledge\/wp-content\/uploads\/sites\/4\/2024\/09\/AISTile-1-275x300.png 275w, https:\/\/innovationspace.ansys.com\/knowledge\/wp-content\/uploads\/sites\/4\/2024\/09\/AISTile-1-940x1024.png 940w, https:\/\/innovationspace.ansys.com\/knowledge\/wp-content\/uploads\/sites\/4\/2024\/09\/AISTile-1-768x837.png 768w, https:\/\/innovationspace.ansys.com\/knowledge\/wp-content\/uploads\/sites\/4\/2024\/09\/AISTile-1-1410x1536.png 1410w, https:\/\/innovationspace.ansys.com\/knowledge\/wp-content\/uploads\/sites\/4\/2024\/09\/AISTile-1-22x24.png 22w, https:\/\/innovationspace.ansys.com\/knowledge\/wp-content\/uploads\/sites\/4\/2024\/09\/AISTile-1-33x36.png 33w, https:\/\/innovationspace.ansys.com\/knowledge\/wp-content\/uploads\/sites\/4\/2024\/09\/AISTile-1-44x48.png 44w, https:\/\/innovationspace.ansys.com\/knowledge\/wp-content\/uploads\/sites\/4\/2024\/09\/AISTile-1.png 1783w\" sizes=\"auto, (max-width: 275px) 100vw, 275px\" \/><\/p>\n","protected":false},"template":"","class_list":["post-183473","topic","type-topic","status-publish","hentry","topic-tag-cht","topic-tag-conduction","topic-tag-convection","topic-tag-discovery","topic-tag-heat-transfer","topic-tag-internal-radiation","topic-tag-radiation","topic-tag-thermal","filter-by-application-discovery","filter-by-application-discovery-explore","filter-by-application-discovery-refine"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_edit_lock":["1726644521:3452"],"_edit_last":["3452"],"filter_by_optics_product":["Lumerical"],"_filter_by_optics_product":["field_64fb192ba3121"],"application_name":[""],"_application_name":["field_64a80903c8e15"],"family":[""],"_family":["field_64a809229a857"],"siebel_km_number":[""],"_siebel_km_number":["field_63ecbffce60db"],"salesforce_km_number":[""],"_salesforce_km_number":["field_63ecc018e60dc"],"km_published_date":[""],"_km_published_date":["field_64c77704499dd"],"product_version":[""],"_product_version":["field_64c776cb4fd2e"],"_bbp_forum_id":["159543"],"_bbp_topic_id":["183473"],"_bbp_author_ip":["2401:4900:889e:21d5:bdb1:1a2f:718f:2770"],"_bbp_last_reply_id":["0"],"_bbp_last_active_id":["183475"],"_bbp_last_active_time":["2024-09-12 08:51:04"],"_bbp_reply_count":["0"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["0"],"_yoast_wpseo_content_score":["90"],"_yoast_wpseo_estimated-reading-time-minutes":["1"],"_btv_view_count":["2498"],"_bbp_likes_count":["1"]},"test":"watchlearnansys-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/183473","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":3,"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/183473\/revisions"}],"predecessor-version":[{"id":183631,"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/183473\/revisions\/183631"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/media?parent=183473"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
