Nasal airflow simulation of patient with septal deviation and allergy rhinitis

Nasal airflow simulation of patient with septal deviation and allergy rhinitis / Joanne Lim Zi Fen
Penyelidikan ini adalah berdasarkan simulasi aliran udara rongga hidung pesakit dengan menggunakan dinamik bendalir pengiraan (CFD). Imbasan CT pesakit dengan kedua-dua sisihan septal dan alahan rinitis diperolehi dari Institut Perubatan dan Pergigian Termaju (IPPT) untuk mengkajikan kesan kedua-dua sakitan ini terhadap rongga hidung manusia. Model tiga dimensi (3D) rongga hidung pesakit telah dibina dengan menggunakan InVeselius 3.0. Model rongga hidung tersebut akan kemudiannya diimport kedalam CATIA V5 untuk pengubahsuaian dan akhirnya diimport kedalam ANSYS FLUENT untuk penyelesaian berangka. Keputusan dan kesan kedua-dua penyakit pada pesakit yang akan dianalisis pada geometri, luas keratan rentas, kadar aliran jisim, tekanan dan halaju magnitud. Kawasan keratan rentas, magnitud halaju dan halaju kontur untuk empat permukaan utama: vestibule, injap hidung, turbinate tengah dan nasofarinks akan dianalisis dan dibandingkan dengan rongga hidung seragam yang siap dibina. _______________________________________________________________________________________________________ This is a research based on numerical simulation a patient’s nasal airflow by using computational fluid dynamic (CFD). The CT scans of patient with both septal deviation and allergy rhinitis is obtained from Advanced Medical and Dental Institute (AMDI) to study the impact of both diseases to human nasal cavity. The three-dimensional (3D) nasal cavity model of the patient is being constructed by using InVeselius 3.0. The 3D nasal model is then being imported to CATIA V5 for modification and finally imported into ANSYS FLUENT for the numerical solution. The results and effects of these two diseases on a patient are being analyzed on geometrical, cross-sectional area, mass flow rate, pressure and velocity magnitude. The cross-sectional area, velocity magnitude and velocity contours for the four main surfaces: vestibule, nasal valve, middle turbinate and nasopharynx are being analyzed and compared with the standardized nasal cavity as well.
