I would like to simulate the airflow of the nose using the following parameters:&nbsp;<\/p>\n<p><strong>Time:<\/strong>&nbsp;inspiration&nbsp;takes 1.9 s and&nbsp;expiration&nbsp;2.3 s (4.2 s for one complete cycle).<\/p>\n<p><strong>Temperature and Humidity:<\/strong>&nbsp;The&nbsp;inspired air&nbsp;had a temperature of 20 C and 30 % relative humidity. The&nbsp;expired air&nbsp;had a temperature of 35 C&nbsp; and a relative<br \/>humidity of 100 %. The temperature of the nasal mucosa<strong>&nbsp;(Wall)<\/strong>&nbsp;increased from 30 C to 34C. The moisture of the nasal mucosa&nbsp;<strong>(Wall)&nbsp;<\/strong>was set to be constant at 100 %<\/p>\n<p><strong>Pressure:&nbsp;<\/strong>To simulate the&nbsp;inspiration,&nbsp;a negative pressure is set in the nasopharynx (<strong>Outlet<\/strong>) between 0 and -10 Pa. This led to a flow speed of up to 2 m\/s around the middle turbinate. For the&nbsp;expiration, the pressure in the nasopharynx (<strong>Outlet<\/strong>) was set between 0 and 10 Pa.<\/p>\n<p>I have successfully generated the mesh and defined the Inlet, Wall and Outlet. I would appreciate help setting the physics step by step. Especially how to make the model dynamic &#8211; expiration and inspiration. Include humidity and heat.&nbsp;<\/p>\n<p>I use Ansys student 2023, also have full version at school.<\/p>\n<p>I hope someone has time for this. Referring me to similar tutorials or posts is great too.<\/p>\n<p>Please check out this study for more information: https:\/\/drive.google.com\/file\/d\/1nEIVnxOQuzmX9-GZLYBOVWuAS3ua5Hup\/view?usp=sharing&nbsp;<\/p>\n<p>Best regards<\/p>\n<p>Looking forward to hearing from you soon<\/p>\n<p><a class=\"wp-colorbox-image cboxElement\" href=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/06\/02-06-2023-1685709209-mceclip1.png\"><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/06\/02-06-2023-1685709209-mceclip1.png\"><\/a><\/p>\n<p>*Can&#8217;t attach the full file for patient privace.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-286868","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["7259","199"],"_bbp_author_ip":["168.143.243.24"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["244"],"_bbp_likes_count":["1"],"_edit_lock":["1685712332:219937"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["286868"],"_bbp_forum_id":["27792"],"_bbp_engagement":["199","7259"],"_bbp_voice_count":["2"],"_bbp_reply_count":["5"],"_bbp_last_reply_id":["287148"],"_bbp_last_active_id":["287148"],"_bbp_last_active_time":["2023-06-05 13:33:26"]},"test":"same-mfptmd-ac-jp"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/286868","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\/286868\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=286868"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
