Research

My research activities focus on modeling of airflow and particulate deposition in the central airways of human/animal lung using computational fluid dynamics (CFD) and aerosol science. CFD models of the lung are created based on mathematical models and/or CT/MRI-scans to achieve a realistic geometry of the lung. For the human lung, a five-lobe mathematical model of the lung, starting at the trachea is currently being used. A three dimensional surface model based on CT-scan images of the rat lung is also under process. In both cases, the fluid volume is extracted from the surface model and meshed in some commercial grid generators; the simulations are then executed using commercial CFD packages where airflow and particulate transport, deposition and removal patterns are evaluated. The results are compared to experimental data from internal/external sources.

This information can be used in risk assessment of human's exposure to airborne materials.
