%X The paper aims to simulate the chemical transport of ammonia vapor with density ¦Ñ = 0.6894 kg/m3 and coefficient of viscosity ¦Ì = 1.015e-05 kg/m-s inside the healthy Indian nose by computational fluid dynamics (CFD) technique and to analyze the olfactory sensitivity. The computed tomographic images of a healthy adultwith normal nasal structure and function was used to built a physically realistic model with the help of Mimics software. Navier-Stokes and continuity equations were solved numerically for steady and unsteady state conditions by finite volume method to determine laminar flow patterns. CFD simulation was performed using Gambit and Fluent software to visualize implications for olfaction. The graphs indicate that only part of the inspired chemical passes through the olfactory airway. The total olfactory uptake for the odorant increased as inlet velocity increased.
