However, a common approach to averaging variables is to use area-weighted averaging for static variables such as static pressure and static temperature, and to use mass flow-weighted averaging for total quantities such as total pressure and total temperature.  The reasoning behind this is that static quantities are more closely related to area while total quantities have a dynamic component that\u2019s related to velocity (which can be related to mass flow). In many cases, there may be little to no difference in using area versus mass flow-averaging.  However, mass flow-averaging only makes sense on boundaries or surfaces through which flow can pass.  On wall boundaries, only area-averaging would be appropriate.<\/p>\n","protected":false},"template":"","class_list":["post-166803","topic","type-topic","status-publish","hentry","topic-tag-4391","topic-tag-averaging","topic-tag-cfx","topic-tag-fluid-dynamics","topic-tag-general-cfx"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_wp_page_template":["default"],"_bbp_last_active_time":["5\/4\/2023 20:20"],"_bbp_forum_id":["27796"],"_bbp_author_ip":["209.182.204.162"],"_btv_view_count":["14975"],"siebel_km_number":["2055639"],"product_version":["19"],"km_published_date":["2018-08-01T00:00:00.000Z"],"family":["Fluid Dynamics"],"application_name":["CFX"],"_bbp_likes_count":["2"]},"test":"articlesansys-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/166803","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\/166803\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/media?parent=166803"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
