Also if thermal phase change is involved, the term (phase change rate) * enthalpy of p.<\/p>\n<p>Here, I am concerned with the model for H_pq when there is thermal phase change.<\/p>\n<p>If there is no phase change, it is simple such as two-resistance model between the phases. But when there is phase change, the two-resistance model is no longer valid, I think, because of phase change at the interface. In this case, how is the H_pq modelled? I can not find any comments on this in any of Fluid documents. The documents have descriptions for only the case of no phase change.<\/p>\n<p>Can anyone give me a clue or guide to this matter?<\/p>\n<p>Kwan.<\/p>\n","protected":false},"template":"","class_list":["post-166743","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_btv_view_count":["1813"],"_bbp_likes_count":["0"],"_bbp_subscription":["249666"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["166743"],"_bbp_forum_id":["27792"],"_bbp_engagement":["25","199","22555","249666"],"_bbp_voice_count":["4"],"_bbp_reply_count":["18"],"_bbp_last_reply_id":["206691"],"_bbp_last_active_id":["206691"],"_bbp_last_active_time":["2022-03-09 10:59:11"]},"test":"khbangkmou-ac-kr"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/166743","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\/166743\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=166743"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
