WebMethod: A three-dimensional nasal cavity model was constructed based on CT images of a healthy Malaysian adult nose. Navier-Stokes and continuity equations for steady airflow were solved to examine inspiratory nasal flow. Results: Around a 0.3% change in the average static pressure is observed while changing from a sitting to supine position. Webwhere $u$ is the (vector-valued) fluid velocity, $p$ is the pressure, $\mu$ is the viscosity and $f$ is a (vector-valued) external force applied to the fluid. This model gives the motion of a fluid in the high viscosity limit and has applications in industrial, geological and biological flows. For less viscous fluids we use the Navier-Stokes equation which …
