Hello,<\/p>\n
I am working on a problem in which mass flow rate is constant. I specified mass flow rate in “inlet” boundary condition. But after seeing the results (velocity and density) I realized that the mass flow rate wasn’t constant. It should be mentioned the fluid is helium and it is considered as an ideal gas. Now I was wondering how I can define mass flow rate as a constant value into pre CFX or if I can’t do that, How can I define velocity or density as a function of each other to keep mass flow rate constant.<\/p>\n
Many thanks in advance<\/p>\n","protected":false},"template":"","class_list":["post-36887","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["9062"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[null],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0","0"],"_btv_view_count":["340"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["36887"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","157590"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["91118"],"_bbp_last_active_id":["91118"],"_bbp_last_active_time":["2019-08-02 10:51:13"]},"test":"hamda"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/36887","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\/36887\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=36887"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
