Dear All, Greetings. I would like to simulate the airflow of the nose using the following parameters: <\/p>\n

Time:<\/strong> inspiration takes 1.9 s and expiration 2.3 s (4.2 s for one complete cycle).<\/p>\n

Temperature and Humidity:<\/strong> The inspired air had a temperature of 20 C and 30 % relative humidity. The expired air had a temperature of 35 C  and a relative
humidity of 100 %. The temperature of the nasal mucosa (Wall)<\/strong> increased from 30 C to 34C. The moisture of the nasal mucosa (Wall) <\/strong>was set to be constant at 100 %<\/p>\n

Pressure: <\/strong>To simulate the inspiration, a negative pressure is set in the nasopharynx (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 expiration, the pressure in the nasopharynx (Outlet<\/strong>) was set between 0 and 10 Pa.<\/p>\n

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 – expiration and inspiration. Include humidity and heat. <\/p>\n

I use Ansys student 2023, also have full version at school.<\/p>\n

I hope someone has time for this. Referring me to similar tutorials or posts is great too.<\/p>\n

Best regards<\/p>\n

Looking forward to hearing from you soon<\/p>\n
