Thus, Tc=Tt for TCC=infinity.  However if user defines too large a TCC value, it will create numerical instability issues. So the default calculation is an attempt to come up with a large enough value for TCC to simulate &#8220;perfect&#8221; thermal contact without causing numerical instability.  Partial thermal contact can be achieved by throttling TCC down to a small value. As TCC gets smaller, the Delta Temp between contact and target surfaces should increase. As TCC approaches zero, q=zero and the interfaces approaches a perfectly insulated condition with no heat transfer.<\/p>\n","protected":false},"template":"","class_list":["post-158073","topic","type-topic","status-publish","hentry","topic-tag-contacts","topic-tag-thermal-conductance"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_wp_page_template":["default"],"_bbp_last_active_time":["06-06-2022 20:20"],"_bbp_forum_id":["27795"],"_btv_view_count":["827"],"_bbp_likes_count":["0"]},"test":"articlesansys-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/158073","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":0,"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/158073\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/media?parent=158073"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
