Therefore, this research studies the changes in velocity magnitudes caused by mucous layer of different thickness and visualize the effects of mucous layer towards nasal airflow. Six different models with various thickness of mucous layer within the range of 0.005mm-0.050mm were implemented in the analysis with mass flow rate of 7.5 to 20 L/min. The results from all the six models were compared with the model with non-mucous effects. Velocity streamlines of non-mucous model are shown for better view of the airflow pattern from inlet to outlet and also circulations can be observed more clearly. Based on both laminar and turbulent airflow simulations at mass flow rate of 10 and 20 L/min, the mucous layer effects are shown to cause significant changes to the velocity magnitude and pressure contours along the nasal cavity. Inclusion of mucous layer does give significant effects to the nasal airflow. Therefore, it should not be neglected in analysis to ensure more accurate information on nasal airflow can be obtained. 2012-10-15T04:32:18Z 2012-10-15T04:32:18Z 2012-02-27 Working Paper p. 276 - 279 978-145771989-9 http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6179020 http://hdl.handle.net/123456789/21354 en Proceedings of the International Conference on Biomedical Engineering (ICoBE 2012) Institute of Electrical and Electronics Engineers (IEEE)
