In this short report we demonstrate the feasibility of using Computational Fluid Dynamics (CFD) for studying the flow in fa.cia.l regions and nasal cavity. A two-dimensional unstructured finite volume flow solver is used. For modelling the turbulence we use a standard k - c: model.
Building diagnosticians routinely use measurements of differential pressures, building and duct system airtightness, and mechanical system airflow when investigating air quality, comfort, durability, and energy use problems in commercial and residential buildings. Unfortunately, wind and other sources of noise can create large pressure fluctuations which significantly increase the variability of these measurements, often to the point where they can not be relied upon in the diagnosis of performance problems, or as quality control indicators.
