<div>Hi, <\/div><div> <\/div><div>I am simulating an aircraft with the engine running, which involves internal and external (engine) flows together. The aircraft is placed in a far-field domain with prescribed boundary conditions, while the engine inlet will have a different boundary condition applied. Both the external domain and the engine are in the same fluid medium (air).<\/div><div> <\/div><div>My main questions are:<\/div><div><\/p>\n

    \n
  1. How should I model the computational domains? If I create a separate fluid volume inside the engine, the inlet and outlet become interfaces, which turn into internal boundaries in Fluent. How do I manage this appropriately for internal-external flow coupling?<\/li>\n
  2. How should I apply the boundary conditions correctly? I need to ensure the boundary conditions for the far-field and engine components are handled properly.<\/li>\n
  3. How do I prepare the geometry for this setup in SpaceClaim? Any suggestions on how to set up the computational domain in SpaceClaim? I want mesh and simulate in Fluent. <\/li>\n<\/ol>\n

    <\/div><div>I’m seeking guidance on the best practices for geometry preparation, domain setup, and boundary condition application in this type of simulation.<\/div><div> <\/div><div>Regards,<\/div><div>Ali<\/div><\/p>\n","protected":false},"template":"","class_list":["post-387355","topic","type-topic","status-publish","hentry","topic-tag-ansys-fluent","topic-tag-boundary-conditions","topic-tag-external-aerodynamics","topic-tag-internal-flow-simulation","topic-tag-spaceclaim"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":["2407:d000:b:2489:f1f4:ff1:754e:3273"],"_btv_view_count":["650"],"_bbp_topic_status":["unanswered"],"_bbp_subscription":["199","276398"],"_bbp_topic_id":["387355"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","276398"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["387750"],"_bbp_last_active_id":["387750"],"_bbp_last_active_time":["2024-10-02 03:41:58"]},"test":"bahaiderknu-ac-kr"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/387355","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\/387355\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=387355"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
